Save up to 3 profitable hours on each job with the innovative Sider. It works quickly and accurately, replacing chalk lines, squares and straight edges. Use it as a scribe or square to mark or score precise lines. Or go straight to cutting with your utility knife in the precisely marked 1/8” (3.2 mm) holes. The Sider comes in 3 sizes to match popular siding profiles and features durable 18-gauge (1.22 mm) stainless steel construction. It’s one smart little tool for even the biggest siding jobs.

Time is money and this saves time!
Huge time saver when cutting siding. Easily pays for itself the first project. Just make sure you buy the right size to match your siding.
