Versatile Stablelock Clamp series 

Fixtureworks has bolstered its array of clamps, modular fixturing and set-up accessories by offering the stable and reliable Stablelock Clamp series.


Fixtureworks Stablelock clampsStablelock Clamps offer a rigid clamping mechanism with a ball and tapered wedge clamping design with spring force for superior mechanical positive clamping. Clamping force is constant and strong no matter the user or the application. A "click feel” at the end of clamping ensures reliable and safe operation while indicator lines on the handle and body align to clearly show when the clamp is locked or unlocked.

Fixtureworks Stablelock Clamps are available in a variety of clamping modes…swing, pull, push, side and thrust. The versatility of the modes offer expansive range of arm travel and length of arm options and makes these clamping choices for a variety of clamping, fixturing and workholding applications…and especially useful for highly repetitive clamping jobs.

The Stablelock Swing Clamps (QLSWW) swing into position and clamp straight down onto the workpiece for direct downward pressure. They feature constant clamping force and a clear clamping point. Turning the handle swings the arm into position. As the arm contacts the workpiece, the spring is compressed, and the tapered surface pushes the balls out to clamp the workpiece. Spring-loaded, these clamps generate constant clamping force with positive locking and spring force.

The handle’s "click feel” at the clamping end point, prevents workpiece damage due to overtightening while indicator lines on the handle and body align to clearly show when the
clamp is locked or unlocked. The arm swings completely out of the way to allow for easy loading and unloading of the workpiece.

The QLSWW swing clamps, with steel electroless nickel plate bodies and lever arms with black plastic covers on the lever, offer ease of operation both in clockwise and counterclockwise motions, while the rotation of an ergonomic handle simultaneously swings the clamp arm out and over the workpiece and into the clamping position (up to 155° rotation). Then a final pressure on the arm draws the arm down and applies direct downward force on the part.

The Stablelock swing clamps are offered in clockwise (QLSWWR) and counterclockwise (QLSWWL) direction. They offer 19 lb. of operating load and up to 224 lb. of clamping force while being only over three inches in height in the clamped position and a little over a pound in weight all adding to their versatility.

In addition to Stablelock Clamps, Fixtureworks offers shaft locking clamps other quick change pneumatic clamping fasteners, quick action spring plunger clamps, handle and levers, knobs and grips, equipment handles, handwheels and cranks, hinges and latches, leveling supports, industrial rubber bumpers, stops and wheels, fixturing clamps, clamping locating systems, work positioning elements, vises, grippers and mechanical linear actuators.
