How To Use Power-Loc Toggle Clamps (Inline or Horizontal)
The Power-Loc dog requires a chamfered 20mm dog hole; we recommend using a trim router with a quality 45˚ chamfer bit, allowing you to perfectly adjust the depth of the chamfer to match the chamfered lip of the Power-Loc dog.
Before inserting clamp into your tabletop, ensure the Power-Loc locking lug is fully retracted into the body (if looking at the clamp upside-down, rotate the locking lug fully clockwise).
Fully insert the clamp assembly into the 20mm dog hole.
Raise the handle to approximately 45˚ to your work surface, which will expose the Power-Loc hex nut for tightening.
Use a 5mm hex driver or key and turn the Power-Loc hex nut clockwise until the locking lug is fully drawn upward and clamps the underside of your table. Do not use an impact driver as this could risk damaging the Power-Loc lug or threads. Finger tight is all that is needed for an extremely secure attachment to your table.
Leaving the hex nut snug, but not over-tightened, allows you to still rotate the clamp 360 degrees about the mounting hole, yet still provides strong hold-down force when clamped down.
To remove, raise the clamp handle to approximately 45˚ and use the same 5mm hex driver or key and turn the Power-Loc hex nut counter-clockwise, which releases the Power-Loc lug and causes it to retract into the body. Pull upward on the clamp to remove.
