Heavy Duty Adjustable Handles
These rugged steel handles provide lasting durability for applications involving frequent positioning, tightening, and holding adjustments. Lift the handle to rotate freely; then release the handle to engage and tighten. These handles are also known as clamping handles. All have a black-oxide finish for mild rust resistance.
Machinable-hub handles permit milling specific holes or keyways in the hub to meet your specifications. They can also be welded in place.
