Jergens HDV Series Heavy Duty Vertical Clamps are designed to be adaptable and durable and to withstand abuse in heavy-duty applications. Model HDV660/FA2 features a flanged base with holes for bolt mounting and a fixed spindle or setscrew position which does not require welding.

The main components are steel, the forked lower handles being precision alloy steel castings, and all axles of hardened steel running in either hardened bushes or directly in the close-toleranced holes of hardened parts. The clamps are finished chemi-black. Supplied complete with setscrew, nuts, and flanged washer.

When welding the swivel base of the ‘Stub Nose’ models to the clamp mechanism ensure that the full length of the adjoining surfaces are welded. Ensure that the welding spatter does not enter the slots which form the forward stop of the mechanism. The handle pivot bolt may be adjusted if required to remove excess free play from the mechanism. Frequent lubrication will extend the life of the clamp.
