Want to find out more about Lock Jaw Ladder Grip?

Lock Jaw will work on the majority of ladders however there are some circumstances where it won’t work.

It will fit on some but not all telescopic ladders. In some cases the bar does not wind down far enough to clamp the ladder and therefore it cannot be used. Although in some cases it does work depending on the make and model.

Climbing ladders are extremely dangerous with hundreds of thousands of people injured from ladder falls.

There are also legal requirements in most countries to secure a ladder.

In Australia:

  • Work Health and Safety Act 2011 – 306L Work on a ladder
  • Work Health and Safety Regulation 2011
  • Managing the risk of falls at workplaces Code of Practice 2021 -WHSQ

The Lock Jaw Ladder Grip can accommodate ladder rails up to approximately 50mm wide.

The product is designed to work as a single unit. We find that persons accessing multi-storey buildings or climbing regularly often opt to use two units (one on each side of the ladder). Two units offer greater stability.

The Lock Jaw Ladder Grip can be used on the majority of guttering, including both traditional and box guttering. Put simply, if you can place the jaws of the unit over the edge of your guttering the device will work.

The Lock Jaw Ladder Grip is supplied with a carabiner which can be clipped onto your belt loop or work belt. So you can maintain 3 points of contact which is best practice when climbing a ladder.
