Product Details

NLG Tether Choke Single Arm

Single-arm heavy-duty choke tether rated to 20kg for large power tools with triggers and straight-shafted tools where a plain choke cinch cannot maintain its position during use. The single securing arm locks the choke in place using NLG Tether Tape, keeping the trigger restriction-free throughout the working period. Extra high-strength webbing, contrast wear indicators, and an optimised V Ring provide the same structural performance as the Tether Choke Original. Approved for use as both a tether point and an anchor point.

How the Securing Arm Keeps the Choke in Position on Power Tools

A plain choke cinch on a power tool can rotate or shift along the tool body during use, particularly on smooth-shafted tools and power equipment with pronounced handle geometry. On a trigger-operated tool, that shift risks the webbing moving in front of the trigger, restricting operation mid-task. The single securing arm solves this by providing a fixed point that is locked with Tether Tape against the tool body, keeping the cinch seated correctly. The arm is positioned away from the trigger during installation, so the trigger remains fully accessible throughout use.

Key Features

Single securing arm: Locks the choke position on power tools and straight-shafted tools, preventing the webbing from rotating or migrating along the tool body during active use.

Trigger-free design: The securing arm is installed away from the trigger side on powered tools. Combined with Tether Tape to hold it there, the trigger remains unrestricted for the entire working period.

NLG Instant Tether System compatible: Works with NLG Tether Tape, which wraps around the securing arm and is stretched during application to activate its self-fusing technology. The Tether Tape is for positioning only and is not load bearing in this configuration.

Anchor point approved: The Single Arm Tether Choke is approved for use as an anchor point as well as a tether point, giving site teams additional flexibility in how it is deployed.

20kg max load, dynamically tested: Same rating as the Tether Choke Original. Tested to 40kg against its 20kg rating via a dynamic 2:1 safety factor test.

Contrast wear indicators: Built into the webbing, these give early warning when the outer layer has worn to the point where the attachment should be retired, well before structural integrity is compromised.

NLG ID serialised technology: Unique serial number per unit. Scan the orange NLG ID tag to access certificates, Declarations of Conformity, and installation videos.

Who Is This For

The Single Arm Tether Choke is used by workers who carry large, trigger-operated power tools at height where a plain choke cannot maintain its position during use. An electrician with a heavy SDS drill on a MEWP platform, a construction operative using a rotary hammer on scaffolding, or a rope access technician with a heavy-duty angle grinder all need a choke that stays where it is placed and does not interfere with the tool's controls. The securing arm, locked in place with Tether Tape, provides that stability. For tools where two points of positional stability are needed, the Twin Arm variant is the correct choice.

Typical Applications

Tethering heavy-duty SDS drills, rotary hammers, and impact wrenches used at height from scaffolding, MEWPs, and elevated platforms.
Securing large angle grinders and disc cutters where the body of the tool is the natural attachment point and a plain cinch would rotate during use.
Providing a trigger-free tether attachment on any power tool where the choke must stay clear of the trigger and control switches throughout the working period.
Deploying as an anchor point on power tools or site equipment where an approved anchor is needed alongside the tether function.
Supporting dropped object prevention programmes on construction and industrial sites where certified, inspectable, serialised attachments are specified for all power tools used above ground.

How to Use

Step 1: Pass the loop end of the webbing around the handle or body of the tool. On trigger-operated power tools, ensure the securing arm faces away from the trigger. Pass the V Ring through the loop end to create a choke cinch.

Step 2: Pull the V Ring end firmly until the webbing seats tightly against the tool body.

Step 3: Cut a length of NLG Tether Tape long enough to wrap around the tool at least five times. Remove the plastic backing strip.

Step 4: Wrap the Tether Tape around the securing arm and the tool body, leaving the webbing catch exposed. Stretch the tape firmly during wrapping to activate its self-fusing technology. The Tether Tape is for positioning only and is not load bearing in this setup.

Step 5: Test the tether point firmly before putting the tool into use at height.

Step 6: Connect an approved NLG tool lanyard rated to at least 20kg to the V Ring only. Confirm the anchor point is rated to the total weight of the tool.

Step 7: After any drop event, quarantine all components and inspect against the NLG Inspection Checklist before returning to service.

Common Mistakes

Positioning the securing arm over the trigger. The arm must face away from the trigger on all powered tools. An arm that restricts the trigger is a safety issue and must be repositioned before the tool is used at height.
Using Tether Tape as a load-bearing element. Tether Tape holds the arm in position only. The webbing cinch and V Ring carry the load. Tether Tape that is torn or missing does not compromise the load path but means the choke may shift position.
Not stretching the Tether Tape firmly during application. Tether Tape requires tension during wrapping to activate its self-fusing technology. Loosely applied tape will not hold the arm securely in position.
Connecting the lanyard to the webbing loop or securing arm instead of the V Ring. The lanyard must always connect to the V Ring.
Ignoring wear indicators. If the contrasting colour beneath the outer webbing layer becomes visible, retire the attachment immediately.

Safety

The Single Arm Tether Choke is rated to 20kg maximum load. The securing arm and Tether Tape are for positioning only. All load is carried through the webbing cinch and V Ring. The lanyard must always connect to the V Ring. On trigger-operated tools, the securing arm must be installed away from the trigger before the Tether Tape is applied. This product is a tool tethering attachment and anchor point only. It must not be used as a personal fall protection component. The anchor point used must be rated to at least the weight of the tool. After any drop event, quarantine all components and inspect against the NLG Inspection Checklist before returning to service.

Maintenance

Inspect the full webbing length for cuts, abrasion, fraying, burns, soiling, and discolouration before each use. Check the contrast wear indicators: if the contrasting colour beneath the outer layer is visible, retire the attachment. Inspect the securing arm for damage or deformation. Inspect the V Ring for distortion, cracks, sharp edges, and corrosion. Inspect the NLG ID label for legibility. Clean with a water-dampened cloth and mild soap solution; air dry away from direct heat and sunlight. Store in a clean, dry environment away from chemicals and solvents. Record formal inspections by serial number using the NLG Inspection Checklist.

Frequently Asked Questions

Q: What type of tools is the Single Arm Tether Choke specifically designed for?
A: It is designed primarily for large power tools with triggers, such as SDS drills, rotary hammers, impact wrenches, and angle grinders, where a plain choke cinch would shift position during use. The securing arm keeps the choke correctly positioned throughout the working period. It also suits straight-shafted tools where positional stability across the shaft is required. For tools where two securing points are needed, the Twin Arm variant is the correct choice.

Q: Why does the securing arm need to face away from the trigger?
A: If the securing arm is positioned over or near the trigger and Tether Tape is wrapped around it, the tape can restrict trigger movement and prevent the tool from being operated correctly. More critically, if the arm shifts into the trigger area during use, it may cause unintentional tool activation. Positioning the arm away from the trigger before applying Tether Tape keeps the trigger fully accessible and prevents contact with the control area throughout the working period.

Q: What is the NLG Instant Tether System and what role does Tether Tape play?
A: The NLG Instant Tether System is NLG's method for securing tether attachments to power tools and equipment using Tether Tape in conjunction with a Tether Choke. Tether Tape is a self-fusing silicone tape that bonds to itself when stretched during application, holding the securing arm firmly against the tool body. It is for positioning only and carries no load in this setup. The load path runs through the webbing cinch and V Ring. Tether Tape that is worn or missing does not affect the load rating of the attachment.

Q: What do the safety standards mean for UK site compliance?
A: The Single Arm Tether Choke is certified to ANSI/ISEA 121-2023, the current international standard for dropped object prevention equipment, and NS 9611:2022+AC, the standard for personal tool attachment systems at height. Dynamic testing at 2:1 safety factor means the product is tested at 40kg against its 20kg rating. CE and UKCA marking confirms compliance with UK and European safety requirements. Independent load test certificates and Declarations of Conformity are available from NLG on request.

Q: What is this product NOT suitable for?
A: It is not suitable for tools weighing more than 20kg. The lanyard must always connect to the V Ring, not the webbing loop or securing arm. The Tether Tape is not load bearing and must not be connected to a lanyard. This product must not be used as a personal fall protection component in any fall arrest or restraint system. The anchor point used alongside it must be rated to at least the weight of the tool.

Q: Can the Single Arm Tether Choke be used as an anchor point?
A: Yes. The Single Arm Tether Choke is approved for use as an anchor point as well as a tether point. When used as an anchor, the same load rating and inspection requirements apply. Always connect the load to the V Ring.

Q: What is the difference between the Single Arm and the Original Tether Choke?
A: The Original is a plain webbing cinch loop with a V Ring, suited to tools with captive handles or holes where positional stability is not a concern. The Single Arm adds one securing strap that is locked in place with Tether Tape, preventing the choke from rotating or shifting along the tool body during use. The Single Arm is the correct choice for power tools with triggers and straight-shafted tools. Both carry the same 20kg load rating and safety certifications.

Q: When should the Single Arm Tether Choke be retired?
A: Retire immediately if the contrast wear indicators show the contrasting colour beneath the outer webbing layer; if the webbing shows cuts, fraying, or significant abrasion; if the securing arm is deformed or damaged; or if the V Ring shows distortion, cracks, sharp edges, or corrosion. Any unit involved in a drop event must be quarantined and inspected before it is returned to service.
