NLG Hammer Tool Tethering Kit - 3kg Tether Loop Bungee Lanyard and Hammer Holster

Who is this for

The hammer tool tethering kit is used by scaffolders, steelworkers, site carpenters, and general construction operatives who use a hammer as a primary working tool at height and operate under a site dropped object prevention policy. It is suited to scaffold erection and dismantling where hammers are in near-continuous use at various elevations, structural steelwork connections and fabrication at height, and any maintenance or civil engineering task where a hammer is used above ground level and a dropped tool presents a hazard to personnel below. The Hammer Holster makes the kit particularly suited to tasks involving repeated put-down and pick-up cycles, where the operative needs both a secure tether and a controlled resting position for the tool during the working day.

Typical applications

• Scaffold erection and dismantling at height, where the hammer is used repeatedly across a shift and must be controlled between fittings to prevent swinging against scaffold tubes or adjacent operatives.

• Structural steelwork assembly where bolts, pins, and connections are driven at elevation and the hammer must be holstered securely between strikes on each connection.

• Shuttering and formwork operations where a hammer is used to drive wedges and pins and must be accessible and controlled throughout the pour.

• Roofing and cladding work at height where the operative is moving across a roof plane and a loose, tethered hammer would swing and create a trip or snagging hazard.

• Civil engineering tasks including kerbing, paving, and drainage installation where an operative is working at a raised level and must keep hands free between hammer strikes.

• Any height safety programme requiring mandatory tethering of all tools above a defined threshold weight, where a standard lanyard alone is insufficient for operator comfort during a full shift.

How to use

Step 1: Confirm the hammer's total weight does not exceed 3kg. Verify the hammer has a captive hole through the handle end for the Tether Loop™ to pass through.

Step 2: Pass the Tether Loop™ 150mm through the hole in the hammer handle and close the barrel connector to secure. The steel loop should seat firmly and not slide out under a manual pull test.

Step 3: Connect the bungee lanyard to the Tether Loop™ attachment point and to the chosen anchor point: a belt loop, harness anchor, or structural anchor point rated for the dynamic load. For hammers above 1.5kg, do not use a wrist anchor - use a belt loop or structural anchor only.

Step 4: Mount the Hammer Holster to the belt, harness strap, or rail at a comfortable hip position. The holster should be positioned so the hammer can be docked and retrieved with one hand without looking down.

Step 5: Confirm the lanyard length allows the hammer to reach the holster docking position without going fully taut. Dock the hammer into the cradle arms and confirm it is retained securely before beginning work.

Step 6: Scan the NLG ID tag system to confirm the kit is within its inspection interval before beginning work.

Common mistakes

• Using a wrist anchor for a heavy hammer: The suggested maximum tool weight for a wrist anchor is 1.5kg. Most club hammers and heavier claw hammers exceed this. For any hammer above 1.5kg, use a belt loop or structural anchor point only.

• Threading the Tether Loop through the wrong point on the handle: The Tether Loop should thread through the captive hole at the end of the hammer handle, not around the shaft or grip. A loop around the grip will slide during use and may release under load.

• Not docking the hammer in the holster between strikes: The holster only performs its function when the hammer is actively placed into the cradle arms. Allowing the hammer to hang loose on the lanyard defeats the purpose of the holster and recreates the pendulum hazard.

• Selecting the wrong anchor height for the holster: If the holster is mounted too high or too low, retrieving and docking the hammer requires awkward movement that operatives will avoid. Position the holster at a natural hip height so docking is as easy as putting the hammer down.

• Continuing to use a kit after a drop event: Following any drop or arrest event, quarantine the full kit including the Tether Loop, lanyard, and holster for a full inspection before returning to service.

Safety

This kit is rated to a system max load of 3kg (6.6lbs) and must not be used with hammers exceeding this weight. Hammers above 1.5kg must not be anchored to a wrist band - use a belt loop or structural anchor rated for the full dynamic load of the tool. The Tether Loop™ must thread through a captive hole in the hammer handle and must not be used on hammers without a suitable hole. This kit is for tool tethering only and must never be used for fall arrest or personal safety. Inspect all components before each use and retire immediately if damage or deformation is visible. In the event of any drop or arrest event, quarantine the complete kit and inspect in full before returning to service. Equipment must be used in accordance with the Working at Height Regulations 2005 and any applicable site dropped object prevention policy.

Maintenance

Inspect the Tether Loop™ before each use for deformation of the steel core, damage to the outer coating, and function of the barrel connector. Check the bungee lanyard for cuts, fraying, and correct function of the carabiner gate. Inspect the Hammer Holster cradle arms for deformation, cracking, and secure mounting attachment. Clean all components with mild soap and water only. Store away from direct sunlight, heat, and chemical exposure. Scan the NLG ID tag system to log inspections and access the NLG Inspection Checklist. Retire any component showing wear or damage before returning the kit to service.
