Gecko Gauges

Gecko Gauges are a labor-friendly product that allows for installers to easily and quickly hang James Hardie siding.  Using a friction-cam clamp system, the gauges are set on the wall and allow the installer to drop lap siding into place and fasten siding HANDS-FREE. The clamps can then be loosened and moved to the next row for fast and speedy installation.  

Gecko Gauges also allow for perfect and equal spacing between each board, ensuring a professional installation. The gauges can be adjusted by as little as 1/4" increments. According to studies, they speed up installation by 47%.
