So good, so worth it.
So good, so worth it. It's like having 4 hands. Going up a ladder with a plank, a nailer, and a level, you still do not need another person to help you with this. If you are working alone, I actually am not sure how you side the house without these. I'm sure you would have to fabricate something similar. Even working with another person, I found these to be amazing. Have the other guy be cut man on the ground, and keep sending you up pieces that you set perfectly each time without having to re-measure. For the first 1/2 of the house I did, were were constantly re-checking level, and our layout and it was a good thing we did, these gauges take getting used to. Make sure you flush the gauge all the way up to the bottom of the board. Sometimes they can sit in an angle, and that 1/8th inch on 1 board can get out of hand in a couple rows if you aren't paying attention. Also make sure you keep the height adjustment bolts tight. I actually lost one of my plastic washers, but was able to find the bolt. Probably not that hard to replace, but just a hassle. If you are going to have these higher than a few feet over anything but grass, buy these and not the plastic ones. I dropped mine on concrete from about 20 feet and dented a corner, still works perfectly. These hold real well, I felt comfortable in how well these held on to slide in 12' boards from a ladder 10' away. Even with the tight grip, there was no damage to any of the boards. The locking handle moves super easy, doesn't take hard wrenching or anything that could be problematic on a really high ladder. Does only 1" increments for reveals. 5",6",7",8". Probably not an issue for most, but something to keep in mind. Still an excellent tool for holding a plank in place, even if I had to fudge a board 1/4"-1/2" or so to adjust my layout. I bought these for 1 siding job and found them to be worth the money. I sold them to my carpenter for 50% cost, but I'm sure you could do better if you wanted.

Good product
These things make installing Hardie board a breeze but I'm not sure one pair will do an entire house. We'll have to see

They do work.
Works just fine. With these I was able to get 2/3 of my house sided over the winter just by working on the relatively few decent days we had. Other reviewers have complained they are made of plastic, so what, a lot of things are made of plastic. I dropped these a couple of times from 20 feet up on a ladder on concrete with no damage. Are they perfect? No nothing is but they do work and make it possible for one person to install siding. They did fall off a couple of times but it was because I didn't have the clamp set right. Again so what. They do work.

Awesome
Worth every penny. Couldn't be happier with how well these work. Not needing an extra pair of hands pays for itself and makes the job so much faster.

Go for the Best!
Tried the rest, sent them all back, and now using the best. The Gecko siding tool is absolutely the best of all the siding tools. It doesn't slip, sag or bow out when you tighten the handle like the others do. If you're doing a siding job be it DIY or you're a Pro, buy these!!

Essential Tools for any DIYer
These things were an absolute life saver. I sided my entire house with them. It would have been insanely difficult without them, i.e., I would’ve needed another set of hands because 12 ft cement fiber boards are friggin heavy. They’re also excellent for taking quick measurements for tricky cuts, e.g., take a small piece of siding and put it on a gauge next to whatever it is that needs a non-uniform. They’re really easy to use. They have a bunch of different settings for different reveals. They don’t scratch the siding. I even used them to help hold up the trim under the eves. Highly recommend!

Worked great!

I’ve been in Aaron whether to buy some of these, I finally bit the bullet and went for them! When they arrived, I was really impressed with the quality, Packaging everything really. They are fully adjustable and Work really well with Hardie plank. They took all the guesswork out and enables you to do the job on your own. Having fitted Hardie plank without these clamps, you really appreciate how good they are when using them. The first job you do will pay for them.

Erleichtert die Arbeit ungemein

extraordinairement, efficace. Pour éviter d’abîmer les clin, il suffit de glisser avant de bloquer les pinces, un petit bout de tissu ou un carré découper dans un écran hPV.
