INCRA Build-It Ratchet Knobs (Set of 4)

Original price £15.95
Current price £11.96
INCRA Build-It Ratchet Knobs allow you to create your own custom jigs and fixtures in minutes. Ratchet knobs are perfect for tool-free operation of any 1/4" T-slot connection. They work in tight spaces and are more comfortable to operate than conventional knobs. These knobs need very little clearance because the lever repositions on the knob’s body, just pull and rotate the lever into open space.  Releasing the lever reengages it with the body. The lever does not actually ratchet back and forth like the one in your socket set. 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. Features
  • Unlimited uses for attaching stop blocks, fixtures, and accessories to any 1/4"T-slot
  • 1/2" hex bolts are perfect for the fences and extender bars on INCRA Miter Gauges and sleds
  • 1" bolts (included) will clamp material 1/2" to 5/8" thick (or up to 3/4" without a washer)
  • Substitute standard 1/4"-20 hex bolts of any length needed for your applications


  • 4 x Ratchet Lever Knobs 1/4-20 thread
  • 4 x 1/4-20 Hex Bolts 1 inch
  • 4 x 1/4-20 Hex Bolts 1/2 inch
  • 4 x Washers
