NLG Drill Harness

Tethering a rechargeable drill at height has historically required a compromise: either untether the drill when the battery runs flat (creating a momentarily unsecured 3kg power tool at height) or send the operative back to ground level for each battery change (losing time and productivity across every shift). The NLG Drill Harness is a patented solution that eliminates that compromise. The TriLock Velcro harness wraps securely around the drill handle while the battery pack slots into the ArmourPlate base below. The tether D-ring is on the harness, not the battery. When the battery runs flat, the operative slides it out of the base, replaces it, and slides the fresh pack in, the harness and all tether connections remain on the drill throughout. Certified to ANSI/ISEA 121-2023, NS 9611:2022+AC, CE and UKCA, dynamically load tested at a 2:1 safety factor, and rated to 3kg.

Why battery changes are the defining problem in rechargeable drill tethering

A compact lithium-ion battery pack can sustain 20 to 30 minutes of continuous drilling before depletion, meaning a full shift at height on a construction or maintenance project involves multiple battery changes per operative per day. Every standard tether method, a strap around the handle, an adhesive D-ring, a wrist lanyard, attaches to a fixed point on the drill body. Changing the battery with any of these in place requires detaching the tether first, which leaves the drill unsecured at height, and then re-attaching it after the change. The drill is at its most vulnerable precisely when it is being handled with one hand and the battery with the other. The patented harness design addresses this by making the tether point integral to the handle harness rather than the battery section, allowing the battery to be exchanged independently.

Key Features

Patented battery-swap design: The tether D-ring is mounted on the harness straps at handle level. The ArmourPlate base cradles the battery pack independently. The battery slides out from below while the harness remains secured on the drill handle , the tether connection is never broken during a battery change.
TriLock Velcro closure: Three Velcro bands wrap in alternating counter-directions around the drill handle, inner, middle, and outer straps each closing in the opposite direction to the previous. The counter-tension geometry resists the rotational and vibration forces generated during active drilling, keeping the harness stable on the handle throughout use.
ArmourPlate base: An overmoulded anti-slip base cushions the battery pack contacts against hard surface contact when the drill is set down between tasks. Provides stability on smooth surfaces and protects the battery from impact damage during normal working-day use.
Universal fit: Fits most standard cordless drills and impact drivers via the adjustable TriLock Velcro straps. Suitable for the majority of pistol-grip power tool formats without brand-specific adapters.
Rear D-ring for lanyard connection: The load-rated D-ring sits at the rear of the harness for direct lanyard attachment to any compatible NLG lanyard within the 120cm length limit and 3kg rated capacity.
ANSI/ISEA 121-2023, NS 9611:2022+AC, CE and UKCA: Triple certified, dynamically load tested at a 2:1 safety factor. NLG ID compatible with unique serial number for formal inspection record-keeping.

Who is this for

The NLG Drill Harness is used by electricians, construction operatives, maintenance engineers, and scaffolders who work with cordless drills and impact drivers at height and need to change batteries during the shift without untethering the tool. It suits any operative whose work requires multiple battery packs per shift, typically elevated installation work, overhead fixings installation, and structural assembly tasks where the drill is in continuous use for extended periods. At 3kg rated load, it covers the majority of standard cordless drill and impact driver models in common site use.

Typical applications

Electricians fitting overhead cable containment, luminaires, or structural brackets using a cordless impact driver on a MEWP platform, where three or four battery changes are required across a shift.
Construction operatives installing structural fixings using a cordless drill on a scaffold platform, keeping the drill tethered throughout each battery change without descending the scaffold.
Maintenance engineers using a cordless drill during overhead pipework or mechanical installation on elevated plant, where battery access is important and untethering creates a dropped object risk.
Scaffolders tightening couplers and fittings with an impact driver on scaffold structures, maintaining continuous tool tethering across multiple platform levels and battery changes.
Any operative whose site dropped object management plan requires continuous drill tethering throughout the working day, including during consumable and battery replacement.

How to use

Step 1: Inspect the harness before every use. Check the TriLock Velcro bands for damage or loss of grip. Check the ArmourPlate base for cracks or deformation. Check the D-ring for deformation. Retire from service if any defect is found.

Step 2: Open the TriLock Velcro closure by peeling back all three bands. Slide the battery pack into the ArmourPlate base from below.

Step 3: Position the harness around the drill handle above the battery section. Close the inner Velcro band in one direction around the handle, then the middle band in the opposite direction over the first, then the outer band in the opposite direction again over the second. Press all three firmly into full engagement.

Step 4: Check the drill harness is fitted securely to the drill by applying firm hand pressure and confirming there is no movement or rotation.

Step 5: Attach the tool lanyard to the rear D-ring. Confirm the connector is fully engaged before beginning work at height.

To change the battery mid-shift: Keep the lanyard connected to the D-ring. Slide the battery out of the ArmourPlate base from below, replace with a fresh pack, and slide the new battery in. The harness and lanyard connection remain on the drill throughout.

Common mistakes

Fitting the harness with only one or two of the three Velcro bands engaged: all three bands in alternating directions must be fully pressed and embedded for the TriLock mechanism to resist rotational forces during drilling. Partial engagement produces a significantly weaker hold.
Fitting to a tool that exceeds 3kg: confirm the drill model's weight before fitting. A tool with a full battery pack approaching or above 3kg overloads the harness and lanyard system.
Fitting to tools without a pistol-grip handle: the TriLock wraps around a handle section above the battery. Tools without a defined handle, angle grinders, circular saws, reciprocating saws, do not provide the handle geometry the harness requires.
Using lanyards longer than 120cm: the maximum compatible lanyard length is 120cm. Longer lanyards generate greater dynamic force in a drop event that exceeds the design specification.
Failing to check the full tug-test after fitting: confirm the harness does not rotate, slide, or lift off the drill body before beginning work at height.

Safety

Certified to ANSI/ISEA 121-2023, NS 9611:2022+AC, CE and UKCA, dynamically load tested at a 2:1 safety factor. Maximum load is 3kg (6.6lbs). Maximum lanyard length is 120cm. This is a tool retention harness only. It must not be used as a personal fall arrest system, fall restraint, or work positioning device. After any drop event involving the harness, remove from service for formal inspection before reuse.

Maintenance

Inspect the TriLock Velcro bands before every shift. Clean debris and contamination from Velcro surfaces with a stiff brush, contaminated Velcro loses grip and reduces the three-band hold. Check the ArmourPlate base for cracks, deformation, or delamination of the overmoulding. Wipe the outer surfaces with a damp cloth. Store away from direct heat and sunlight. Record formal inspections against the serial number at intervals appropriate to frequency of use and site conditions.

Frequently Asked Questions

Q: How does the battery change work without untethering the drill?
A: The TriLock Velcro bands secure the harness around the drill handle, above the battery section. The battery pack sits in the ArmourPlate base below the handle straps. The tether D-ring is on the harness at handle level, not on or near the battery. When the battery runs flat, the operative slides it downward out of the ArmourPlate base, inserts a fresh battery from below, and slides it into position. The harness straps remain on the drill handle and the lanyard remains connected throughout the process.

Q: What drills and impact drivers does this fit?
A: The harness fits most standard pistol-grip cordless drills and impact drivers with removable battery packs. The TriLock Velcro adjusts to fit the handle diameter of most models from major manufacturers. Confirm the drill weighs no more than 3kg with a full battery before fitting. Tools without a pistol-grip handle, angle grinders, circular saws, and similar formats, are not suitable.

Q: What certifications does this carry?
A: Certified to ANSI/ISEA 121-2023, NS 9611:2022+AC, CE and UKCA, dynamically load tested at a 2:1 safety factor. Each harness carries a unique serial number with NLG ID compatibility. This is also a patented product design.

Q: What is this not suitable for?
A: It must not be used with tools exceeding 3kg or with lanyards longer than 120cm. It is not suitable for tools without a pistol-grip handle, including angle grinders, circular saws, and straight-body tools. It must not be used as a personal fall arrest, fall restraint, or work positioning device. After any drop event, remove from service for formal inspection.

Q: How does the TriLock mechanism keep the harness secure during active drilling?
A: Active drilling generates both rotational torque (as the chuck turns) and vibration through the handle. A single Velcro band or a single strap under these conditions can work loose progressively through each drill cycle. The TriLock mechanism wraps three bands in alternating directions, inner, middle, outer, each opposing the other. When rotational or vibrational force acts in one direction, the opposing bands create counter-tension. The three-band counter-direction geometry resists loosening under the combined rotational and vibrational forces that standard Velcro wraps cannot resist alone.

Q: What does the ArmourPlate base protect against?
A: The ArmourPlate is an overmoulded elastomeric base that cushions the battery pack contacts from hard surface impact when the drill is set down during a shift. Battery pack contacts are the most vulnerable point of a lithium-ion power tool, hard impacts on concrete, metal decking, or scaffold boards can damage the contact terminals and reduce battery life significantly. The ArmourPlate also provides anti-slip friction on smooth surfaces, keeping the drill stable when set down without a holster.

Q: When should the harness be retired from service?
A: Retire if any of the three TriLock Velcro bands show delamination or consistent failure to grip on the tested handle. Retire if the ArmourPlate base shows cracks, deformation, or separation of the overmoulding. Retire if the D-ring shows any deformation. After any drop event where the harness has arrested a falling drill, remove from service regardless of visual condition and arrange formal inspection.
