M'a sauvé la vie une fois !
Absolument top mais trop cher, beaucoup trop cher. Je m'en sers aussi pour bloqué la chute de l'échelle de toit en aluminium qui est très lourde.En gros je pense que ce truc m'a sauvé la vie au moins 1 fois.
Pricy, but that's the cost of being safe!
If you've read many of my reviews, you will quickly realize I do the majority of my own work.I painted our 3800 square foot house.I used this to paint the upper eve of our home.I can't over emphasize my fear of heights! I felt completely safe knowing This was helping hold my ladder.
Bastante seguro.
Sujeta adecuadamente y se puede regular tanto en grosor como en anchura de perfil de la escalera. Lo que echo en falta es que la L hexagonal sea un poco más larga.
Great construction
I inspect property damage insurance. this is wonderful to hold my ladder safely and secure to the gutters. Gives you the ease of not worrying about if the wind will knock down your ladder; or if you might kick it out from underneath you.
Worth every penny, won’t be my last!
No need for that unsafe ratchet strap anymore!
Should be the industry standard!
As a tradesman, getting on & off roofs all day long, this has made such an impact on ladder safety for me. I’d have to strap ladders down with bungee cords, etc & sometimes I’d just throw the ladder up & pray the wind would behave, because of how much of a pain it was to strap down. Read this: BUY ONE. It will make your life so much easier & honestly it will pay for itself in the long run. Most importantly though, it’ll keep you safe. Definitely worth it. I was able to show mine off to the company I work for & now they’ll be implementing it as a company provided tool. That’s how awesome this product is. No bs.
The Amazing LockJaw
Best. Invention. Ever. The problem with climbing around on a 2+ story roof is getting back onto to the ladder. This amazing device secures the ladder to the gutter so it doesn’t budge. I had to replace several full shingle sheets that blew off my roof in a wind storm. The estimate was $500….but I recently had my knee reconstructed so I wasn’t sure about doing it myself (the problem is always getting back on the ladder…..especially with a questionable knee). The LockJaw literally made the ladder part of the roof so it didn’t budge. My wife is getting annoyed because I won’t stop raving about it (but not too annoyed since the roof was fixed for just a few bucks and she isn’t a widow 😅). Buy this!!!!! Your life might depend on it!!!! Worth every penny!!!* I was NOT compensated for this review. I rarely write reviews but had to here.

Frequently asked questions
Does it stop the gutter getting crushed?
There are rubber pads on the clamp mechanism to prevent scratching. Once the Lock Jaw is installed the ladder won’t move
Which ladders will Lock Jaw work on?
Lock Jaw will work on the majority of ladders however there are some circumstances where it won’t work.
Will Lock Jaw work on telescopic ladders?
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.
Why use Lock Jaw?
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
What is the widest ladder rail that the product will fit?
The Lock Jaw Ladder Grip can accommodate ladder rails up to approximately 50mm wide.
Do I need to use one or two Lock Jaw Ladder Grips?
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.
What types of guttering can the device be used on?
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.
How do I carry the device up the ladder?
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.
