Achieve Positive Locking at Any Position
With Adjustable Locking Hubs

New Variloc® Adjustable Locking Hubs, in stainless steel or plastic, are available from Carr Lane Mfg. Co. These high strength hubs are positive locking at exact increments...10 or 15 degrees, depending on the model.

Applications include adjustable or rotating fixtures, welding fixtures, trunnion mounting, adjustable and/or foldable handles, adjustable part trays and shelves, adjustable and/or flip-up work surfaces, positive positioning of spotlights or nozzles, and collapsable structures.

Medical applications include folding and adjustment mechanisms for wheelchairs. The hubs can also act as an end effector on medical equipment to allow the operator to change the angle of operation.

Panels can easily be flipped out of the way with a simple push button activation, improving ergonomics of machine control panels, vehicle workstations and touch screen adjustment. In fact, the hubs allow versatility whenever a design requires adjusting, reclining or folding, and are compatible with standard tubing.

Steel and Stainless Steel Adjustable Locking Hubs are each available in two different styles, including an inline version, which allows locking anywhere within 220°, and an offset version, which allows full 360° rotation. Once locked, the hub becomes an absolutely rigid joint, able to withstand 80 ft.-lbs. of torque (5:1 safety factor).

Plastic Locking Hubs are lightweight and economical, and withstand 7 ft.-lbs. of torque.

In the unlocked position, the hub is free to rotate. Hub extensions and a variety of mounting options are available.
