Incra BKNOBS2 Build-It Ratchet Lever Knob Kit, Black

The Ratchet knobs are ideal for tool-free operation of any 1/4" T-slot connection. Able to work in tight spaces and are comfortable to operate, unlike the conventional knobs. These knobs need very little space because the lever repositions on the knob’s body; just pull and rotate the lever into open space. Releasing the lever will engage it with the body. The lever does not actually ratchet back and forth like a socket will.Ideal for the fence mount and extender bars on INCRA Miter Gauges, the T-slots in INCRA Miter Sleds, jigs assembled with Build-It components and INCRA T-Track and T-Track Plus.
