Steady on Every Climb.
Home Every Night.
You know the moment the ladder starts to slide side by side on a gutter. Lock Jaw clamps to the gutter in 5 seconds so it can't slide or kick out - both hands back on the work, and the confidence to finish the job and get home to your family.
A Ladder That Shifts Is
A Fall Waiting to Happen
An unsecured ladder can slip out from under you and cause a serious fall.
Ladders Kick Out
Slippery gutters can cause ladders to slide
Having someone hold the ladder costs time and money
Lock the Ladder to the
Gutter Itself
A spotter gets tired. A strap works loose. Lock Jaw is different - it clamps straight onto the gutter and turns the one thing that moves, your ladder, into the one thing that can't. Five seconds, no tools, no second person.
You're the One on the Roof.
We've Got the Ladder.
Lock Jaw doesn't climb the roof. You do. It just makes sure the ladder's got your back on every rung.

- Brace it with your body - or tie up a spotter
- One hand for the work, one for the ladder
- Every climb is a gamble
- Clamped to the gutter - can't slide or kick out
- No spotter: one person sets up and climbs
- Both hands free for the actual work
- Steady every time - home safe

"I've used Lock Jaw Ladder Grips to secure my ladder to the roof gutter for many years. Very safe and effective, and long lasting. I'd highly recommend this safety device."Glenn C. · Verified buyer
"Quality safety tool that actually works so well. My mates see it and buy one too."
"Love my ladder grip - it's amazing how it holds the ladder. Very secure. The D-ring on the bottom even helps hold my coating and power-washer hose."
"I'm at that age where I probably won't bounce very well, and being here for my family means more than a hundred bucks. Some of these gutters are very slippery - I've had some close calls. Not anymore."

Roofer FAQs
Will it damage my customer's gutters?
No. Lock Jaw uses rubber-padded clamps on all contact points. It grips firmly without scratching, denting or distorting aluminium, steel or copper gutters. Not for use on plastic or vinyl gutters.
What gutter sizes does it fit?
Lock Jaw fits the vast majority of standard residential and commercial gutters - typically 4" to 6" profiles.
Does it work on steep-pitch roofs?
Yes. Lock Jaw was designed specifically for steep-pitch roof work, where lateral ladder movement is most dangerous. The clamping mechanism holds firmly regardless of roof pitch.
Can I move it quickly between placements?
Absolutely. The quick-release design lets you unclamp, reposition and re-secure in under 10 seconds - ideal when you're working around the perimeter repeatedly.
What ladders is it compatible with?
It works with the majority of extension and multi-position ladders roofing crews use, including telescopic. Check the rail spec on the product page before you order.
How fast is shipping?
Orders ship quickly from within Australia, so you're protected on the very next job - not weeks from now.
