Many everyday power tool sawing or routing tasks involve cutting a straight line. There is always the problem of how best to guide the tool along a straight cutline. These guide clamps are a perfect alternative to trying to use a straight bit of scrap wood and a couple of G-clamps, which invariably will get in your way. UJK Technology Progrip guide clamps are a purpose-made, obstruction-free solution. UJK Progrip guide clamps offer a versatile and secure method for guiding routers, circular saws, jigsaws etc. The positive clamping mechanism sits below the top of the clamp. The mechanism has 3 progressive clamping pressures, allowing for final positioning before securely locking. It exerts plenty of pressure ensuring the guide clamp will not move in use. The guide clamp’s extruded aluminium profile is rigid. The guide clamp will not bow in use ensuring your power tool will follow a straight line, not a curve.
