Manual Work Supports

Work Supports & Rest Buttons

Product Information

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 Adjustable Handle can be reset to any angle for best leverage.

Manual Work Supports are available in three sizes, with either an inch or metric tapped plunger. To use a contact bolt, see Related Products below. For fixed-height contact bolts, see Screw Rest Pads or Screws Rest Buttons. For adjustable contact screws, see Knurled Screw Jacks.

Application Information

Low profile allows reaching far underneath low workpieces.

Ideal for holding in hard-to-reach places like underneath this wash. The work supports can be positioned to allow convenient access of the handle.

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

Loading with Plunger Extended

Before loading, turn handle counterclockwise to unlock plunger, allowing the plunger to float. After loading, lock plunger manually at the proper height by turning the handle clockwise.

Loading with Plunger Retracted

Before loading, turn the handle counterclockwise to unlock, manually depress the plunger, then turn the handle clockwise to lock in retracted position. After loading and clamping, turn handle counterclockwise to release the plunger, then re-tighten as soon as the plunger extends into position.
