Manufactured using precision machined aluminium extrusion with brass fittings. The reference surface is embedded with a 19mm rare earth magnet and covered with a low friction UHMW pad. The magnets keep the saw aligned; the pads allow the saw to slide easily against the reference surface. The clamp can accommodate material from 6mm to 25mm thick. The guide can be used with virtually any backless saw, however the Veritas dovetail saw is specifically designed for the job; with a 50 x 215mm, 22tpi blade, effective in both cross and rip cuts.
