Nonmarring Adjustable Handles
The brass tip on the end of the threaded stud prevents damage to surfaces in 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. Made of plastic, all of these handles resist oil, grease, and solvents. They are reinforced with fiberglass for strength. Mount them into a threaded hole.
