Review: Awesome product - Worked great! Review: One of the best inventions for putting up Hardie board planks! - We are currently putting Hardie board planks up and these make it so easy you can do it yourself! They slide in under the second board and space it where it you want it. It is adjustable to make the spacing different sizes as to if you want a straight line on either side of a door or window. They work great! Originally bought a set at Lowe's, but returned them as I needed to get a building permit to do this work so I had to wait. Then I found them on desertcart. Less expensive and shipped out immediately. If you are a homeowner as I am and doing this work yourself, don't forget to wrap your house with the correct tape and use the Gecko's. They make putting it up so easy! ## Features - PRO GRIP CLAMP: Ideal for one-person installation this siding mounting block gauges and support the next course for nailing, with virtually no layout time.

D Plastic LP Siding Tool Green 2 pk - Image 1](https://m.media-amazon.com/images/I/71yr-IoF5nL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Will this work for 12" x 16' smart siding?** A: I don't know if this product will work on a 12" siding although it does have a height adjustment on it, but this product works best with siding up to 8 1/2" X 16'siding. **Q: Shipping to new Zealand** A: we only ship to the continental US **Q: Does the 7/16 gauge work on 3/8 siding or does one have to get both for that 1/16 difference?** A: The problem that you would have is that the gauge would not grip the 3/8" siding. You could shim the lower end of the gauge by gluing a 1/16" thick piece of laminate, such as a piece of Formica, to the gauge. Contact adhesive, or double sided tape would likely suffice as an adhesive. That should suffice for your use of the Gecko Gauge. **Q: Will this work with 6" beveled western cedar?** A: I don’t know what thst looks like but they are adjustable ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome product *by G***F on March 7, 2026* Worked great! ### ⭐⭐⭐⭐⭐ One of the best inventions for putting up Hardie board planks! *by M***E on May 10, 2024* We are currently putting Hardie board planks up and these make it so easy you can do it yourself!
