Review on Positioning Aluminium Woodworking Carpenter Cabinets Industrial Power & Hand Tools by Marco Habersham

A good solid right angle guide will not flex when the box is clamped. It's easy to use and the handles easily adjust with your fingers. You can also use it with spring clamps or quick release clamps for quick setup. It also has a series of countersunk mounting holes so you can mount it on your desk with the horizontal desk clamps for quick setup for repetitive operations. Nicely made with no sharp edges to cut yourself on, but I would recommend that you place self-adhesive rubber or felt pads on the T-clamp blocks so they don't scratch the surface if you overtighten.
