    Cushioned Solid-Surface Grippers

    Topped with textured urethane, these grippers hold workpieces steady without digging into the surface. They’re often used to support finished parts and oddly shaped workpieces. Rather than a through hole, these grippers have a solid surface that grips your workpiece evenly and shields the mounting hole from debris. However, they can be harder to line up than grippers with a through hole. Mount them from the bottom with a socket head cap screw.
    The lower the durometer of the gripper surface, the more cushion it provides; the higher the durometer, the more wear it can withstand over time.

    Vibration-Damping Sandwich Mounts with Inserts

    Install these mounts between studs inside or under equipment. Our jack-of-all-trades option, they isolate vibration to protect circuit boards, air compressors, and everything in between. They also muffle noise so you can work or hold a conversation around buzzing and thumping machinery. With reinforcing metal bonded to the rubber, they'll support weight when mounted underneath equipment (Cap. per Mount).

    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.

    Knife Edge

    Install these clamps into a slot in your fixture to grip at the bottom of workpiece edges, giving the cutting tool maximum access to your workpiece. Thread the clamp into a tapped hole and give the center screw a half turn for quick clamping.
    Blunt Edge—Clamps with a blunt edge are less likely to mar your workpiece.
    Knife Edge—Clamps with a knife edge bite into your workpiece for faster and more aggressive machining.
    Brass Head—Clamps with brass heads are nonmarring when used with steel and aluminum workpieces.
