Gibraltar DKL25-G Locking Knob Handle Plunger 1/4-20

Product Description

The GIBRALTAR DKL25-G is a locking knob handle plunger designed for use in positioning, clamping, and indexing applications found in industrial machinery, fixtures, and equipment assemblies. It features a Delrin knob head and a spring-loaded plunger mechanism with an initial end force of 0.12 pounds and a final end force of 0.36 pounds. The body measures 0.63 inches in length, and the maximum plunger diameter is 0.16 inches. The 1/4-20 thread pattern allows for straightforward installation into tapped holes. This type of hardware is typically installed by machine builders, millwrights, and maintenance technicians working on positioning fixtures and adjustable assemblies.

The DKL25-G is suited for light-duty positioning and locking applications in industrial, commercial, and specialty equipment environments. The plunger projection of 0.13 inches engages detents or recesses in mating components to hold position under low spring load. The locking knob style provides a positive handgrip for manual adjustment without additional tooling. This plunger is commonly used in panel assemblies, sliding fixtures, drawer stops, and adjustable equipment frames where repeatable manual positioning is required.

Installation Notes

Installation is performed by threading the DKL25-G into a pre-tapped 1/4-20 hole by hand or with a wrench sized to the 1/4 inch hex. Ensure the mating surface includes a properly sized detent or recess to accept the 0.16 inch maximum plunger diameter. De-energize or lock out any moving equipment before servicing or replacing plunger hardware on active machinery. Do not exceed the rated end force range when specifying this plunger for load-bearing or safety-critical locking applications.
