Eliminate wobble while cutting with your router by mounting this Durable 3/8'' Thick Polycarbonate as a router base! The strong, support base keeps your router level and stable during the toughest of cuts. The polycarbonate may be cut, drilled, or routed to fit any application you need, but is strong enough to withstand extremely high impact, such as flying wood chips. Plus, the clear transparent sheet lets you keep a close eye on what you are doing (the clear base is not a substitute for safety glasses). 3/8" piece comes in an approximate size of 12" x 12".
