Contractor 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 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 contractor 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.

Secure in
Three Steps
Position
Place the ladder against the gutter and position Lock Jaw over the gutter, with the bar behind the ladder rail.
Clamp
Open the handle, position the jaws firmly under the gutter lip, then push the handle down until it clicks securely into place.
Secure
Adjust the bar assembly until it sits firmly against the ladder rail. Check that Lock Jaw is fully clamped and the ladder is secure.
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.
WHS Compliance
for Contractors
Safe Work Australia guidance recommends that workplace ladders are positioned on a solid, stable surface and secured to prevent slipping or displacement. Lock Jaw is designed to help secure your ladder at the gutter, adding stability while you work at height.
