Dual-Clamping Fixture Clamps

Set one of these clamps between two workpieces in a fixture and tighten the screw to push the clamp's sides out for a secure hold. The minimal contact leaves more of the workpieces free for machining.

Machinable Dual-Clamping Fixture Clamps

Machine these fixture clamps to match the contours of your workpieces for a stronger grip. Place the clamp between the two workpieces in a fixture and tighten the screw to extend the sides of the clamp, creating a secure hold against both workpieces. Minimal contact with the workpiece leaves more of its surface accessible for machining. Each clamp comes with a locking plate to keep the clamp rigid while machining it to fit your application.

Ball-Lock Quick-Change Fixture Clamps

Build these components into fixture plates, machine subplates, and tombstones for quick changes. The system clamps and locates at the same time for accurate positioning with repeatability of ±0.0005". Components are compatible with Jergens Ball-Lock, Carr-Lane Carr Lock, and Kurt PinLock quick change systems.

For accurate positioning, at least two sets of clamps, liners, and receivers are required. Install the receivers in the base plate and the liners in the fixture plate. Then line up the two plates, insert the clamps, and tighten their screws to secure the fixture in place. If more holding capacity is needed, use additional clamps and receivers but omit liners to prevent the clamp from getting stuck in the fixture plate.

Push receiver plugs into unused receivers to prevent chips and coolant from accumulating during machining. When installed, plugs sit flush with the surface of the fixture plate. To remove, thread a screw into the tapped hole in the center and pull up.

Adjustable-Height Floor Locks

Set these floor locks to the height you need to compensate for uneven and sloped floors. Use them to stabilize carts, trucks, workbenches, and other mobile equipment during loading and unloading. Floor locks bolt to the underside of your equipment and have a spring-loaded base with a nonskid floor pad to keep equipment stationary.

Note: Floor locks are not load rated. They are designed to brake your equipment in place, not lift it off the floor.

Hydraulic Lift Caster

Hydraulic Lift Caster

Hydraulic lift casters allow you to move heavy equipment, then set it in place on leveling feet. To use, mount the casters and pump on T-slotted framing and connect the casters to the pump with the included tubing. Use the hand crank to raise and lower the casters.
