It is adjustable at 1/4-inch increments for 4 to 8-inch siding reveals. Our gauge has a patented non-marring friction cam mechanism that securely holds a 12-foot piece of fiber cement siding for hands-free nailing. It is constructed from heavy-duty plastic and includes a rubber padding material on the locking grip, ensuring that it won’t scratch or mar pre-painted siding. At PacTool, we are known for our outstanding line of exterior products in the construction, renovation, and remodeling sector and take pride in providing exceptional solutions that help to reduce fatigue and frustration for craftspeople, artisans, and DIYers. From the Manufacturer For siding installation, similar to SA902, but this newer model will not scratch pre-painted siding. Heavy-gauge plastic helps avoid marring the painted surface. One person can install fiber cement siding while ensuring each course stays level. Adjusts for a 5, 6, 7 or 8-inch reveal. Sold in a set of two. Review: Excellent product! Buy these! - 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. Review: Labor Saver - Works fantastic!

There is a model SA902.12 that is made specifically for use on the 12". It is basically the model SA902 with a pair of long aluminum extensions included in the package. Since this model is made of aluminum it isn't recommended for use on the pre-finished siding as the aluminum tends to leave marks. **Q: What makes this zone 10 specific?** A: http://www.jameshardie.com/dealer/hardiezone.shtml + http://www.jameshardie.com/homeowner/hardiezone-video.htmlThe Zone 1 - 5 product has a specific drip edge design and since this tool clamps at that edge, you use it on zone 6 - 10 products. **Q: Would these work installing the big 0.312-in x 48-in x 96-in hardiepanel vertical fiber cement siding panels?** A: These are for panel siding … clamps to Z Flashing to hold up the panel. https://www.amazon.com/dp/B001PBJ6QM?tag=price125420e-20&ascsubtag=wtbs_60358245085322c828fd7606 **Q: Will this work with 1in by 8in cedar bevel ?** A: Probably not. It’s only for 5/16 siding ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent product!
