PacTool Gecko Gauge, The Original Home Siding Installation Kit - For Use with 5/16 Inch Fiber Cement Siding and James Hardie Siding, Includes 2 Gecko Gauge Clamps

I started siding my shed without these clamps and ordered them about halfway through the project. Buying these clamps was some of the best money I’ve ever spent. I’d say the company’s estimate of saving half the time during labor is conservative, and your accuracy is 100% with these clamps. I can easily hang 12’ lengths of Hardie plank alone with these. I’m in the process of replacing all the siding on my home and these clamps are a lifesaver. They’re easy to adjust the face reveal, which locks in with the bolt and nut. I’m glad it’s an adjustment that locks with a bold and but because you wouldn’t change your face reveal in the middle of a job typically, and the way the tool is designed you never have to worry about the clamps coming out of your setting. The clamps are plastic, but it’s a very high quality plastic and the clamps are extremely well made. Excellent design and extremely well made product. These make hanging siding so much easier I’d buy them even for a small project. For the amount of time and effort they save these clamps are awesome. Neighbor brought me over a competitors product, the aluminum round ones if you know which ones I’m referring to, but after using both these gecko grips made his look cumbersome and slow. Best product on the market for hanging siding. I have no idea why anyone wouldn’t rate these at 5 stars. Probably one of the best tools I’ve ever owned.

If you are considering installation of Hardie siding, this rather simple tool is a must have. Yes, they are not inexpensive considering their simplicity, however, you will experience a very significant savings in time and effort which more than offsets the $60 investment for the pair. You do need two for proper and accurate installation of siding. Very fast,easy to use, accurate, and durable unless dropped onto a very hard surface like concrete. The body is made of a tough plastic but it will crack if mistreated. Don't let this happen and you can use them for a very long time. Not much to wear out really. We did drop one off a ladder from about 15 ft onto a concrete pad. The body cracked on a diagonal approx in the middle of the tool. Using Loctite brand two part epoxy adhesive clamped up overnite, we successfully repaired the crack and were able to use the tool to complete the job. There is no sign of the repair failing after approx 400+ use cycles. It is much better to gauge overlap spacing from the bottom of the plank rather than from the top as the major competitor of this brand does. We set our Gecko gauges for a 6" over lap and had no trouble maintaining consistent spacing which is very important to a high quality install. Check your work for level every 4th or 5th plank as there is some minor variation in the Hardie plamks. It is easy to correct for this with the gauges. Level variation is observable if over 1/8th inch, so check your work as you go! I will not do another Hardie siding install without these "Gecko" gauges. Highly recommended.

As a homeowner, we recently embarked on a siding project for our house, and I cannot express enough gratitude for the PacTool SA903 Gecko Gauge Siding Mounting Kit! This incredible tool has been an absolute lifesaver for my husband, allowing him to complete the siding installation quickly and effortlessly, all on his own—no need for an extra pair of hands! Before discovering the Gecko Gauge Mounting Kit, my husband was facing the daunting task of installing the siding with the help of a friend. However, this kit has truly revolutionized the way he works. The genius design of the Gecko Gauges allows him to securely hold and gauge the siding boards in place, freeing up both his hands to fasten them securely without assistance. The result? A seamless and professional finish that looks like it was done by a seasoned contractor. One of the most remarkable aspects of this kit is its user-friendly nature. My husband had no prior experience with siding installation, but with the help of the detailed instructions and a few online tutorials, he quickly became a pro. The Gecko Gauges are adjustable and fit various siding profiles perfectly, ensuring a snug fit every time. The time-saving benefits of the Gecko Gauge Mounting Kit cannot be overstated. Without the need to wait for a helper or juggle cumbersome tools, my husband's productivity soared. What once seemed like a never-ending project was completed in record time, giving him more leisure time to spend with the family. In conclusion, if you are planning a siding project and are hesitant about the challenges of working alone, the PacTool SA903 Gecko Gauge Siding Mounting Kit is an absolute must-have. It transformed what could have been a stressful and time-consuming task into an enjoyable and rewarding experience for my husband. I wholeheartedly recommend this kit, and I can confidently say it will become an indispensable part of your toolbox too!

Works fantastic! Great find and a time saver

No question this thing saved me some time and effort. It slides under the next piece of siding below the row you want to align, and has a groove the new piece sets into. I used it to hang Hardie Shingles by myself. Set the reveal within a couple of inches and rip a board to set the bottom of your shingles to the right total reveal. Rip several boards of various lengths so you can fit in between windows, eaves, etc... Pros: One person operation, set it up and forget. Durable, dropped from high scaffold. Easy to use. Does not slip once you have it set under siding correctly. Super fast with two people, each person sets it, hangs the siding, nails and repeats. Cons: With shingles, it can flex the shingle out and some of them did not flatten back all the way again. Some of the shingles wouldn't stay flat by themselves anyway without this sliding under it, so its not the end of the world but it seemed to make it slightly worse if the shingle was prone to popping out.

What a game changer for running hardie plank siding! It makes it so simple to set and forget and get the job done!

These are awesome! Once your first row is perfectly level, use these gauges and the rest will follow! As long as you insert and set these perfectly, which is very easy to do, your siding will line up flawlessly. Fantastic invention...HUGE time saver. You don't have to measure out or level placement of every board...this tool does it for you. Just set the gauges, insert the plank and nail it in place. We used 12 ft siding planks which can sometimes warp in the middle (it doesn't matter the manufacturer, they all do it)...these gauges can fix that too. Set the gauges 4-6 inches from each end of the plank for the first nailing. Then move the gauges toward the center of the plank about 3-3 1/2 ft from each end...make sure the gauges are fully inserted onto the finished plank...adjust the plank you are nailing down- if the plank is higher than the 'rest' on the Gecko- push down until it rests properly and nail it in...likewise if the plank is lower than the 'rest' - push up until it rests properly on the Gecko gauge and nail it in place...could't be easier. No sweat, perfectly alligned siding!!!

I would never side a house without these ever again! No having to hold up a template key while fastening. Could not do solo siding work before them…now I can! Working really well with James Hardie fiber cement planks which are fairly heavy, but these Gecko clamps perform perfectly with that product.

Indispensable pour bien poser son bardage. Fiable et facile d'utilisation

Geniale Montagehilfe für Hardie oder Cedral Fassaden Paneele und macht die ein Mann Montage möglich

I had to purchase these through Amazon US as these couldn’t be purchased anywhere in the U.K. when I wanted to buy them. Somebody told me about these clamps at work. I had a look On the internet and found them here on Amazon. They are plastic but well made, they’re light and they clamp into the boards very well. You do not need to push the lever all the way up, just up enough so they nip up onto the board. I read somewhere if you keep pushing the lever all the way up it prematurely wears out the pads that grip into the board so bear that in mind. They make fitting cladding a breeze it’s so much easier, just pop your board on the clamps and you have both hands free to fix it and check your running straight and level etc. Totally eliminates the need for a second person. No regrets at all with this purchase they’re brilliant.

una excelente calidad

Used these to install 7.5mm HardiPlank, great addition to the kit. Well worth the investment
