Low profile allows reaching far underneath low workpieces.

Mounting slot allows stacking other components, such as this Cam Edge Clamp, on top of the support.

FEATURES: Spring-extended work support with an extremely low profile. Ideal for supporting in hard-to-reach places, because the handle can be positioned for convenient access. Turning the handle counterclockwise unlocks the plunger, allowing the plunger to float. Turning the handle clockwise locks the plunger .If desired, the plunger can be locked in retracted position before loading, for easier loading of light parts. The zinc die-cast Adjustable Handle can be reset to any angle for best leverage.

SIZES: Available in three sizes, inch or metric — see Dimensions page for part numbers:
 5/16-18 or M8
 1/2-13 or M12
 5/8-11 or M16
