Gibraltar SDKL38-G Locking Knob Handle Plunger 3/8-16

Product Description

The GIBRALTAR SDKL38-G is a locking knob handle plunger designed for precision positioning and locking applications in industrial, HVAC, and mechanical assembly environments. Threaded at 3/8-16, it features a maximum plunger diameter of 0.25 inches and a Delrin knob handle for a firm, tool-free grip. The plunger delivers an initial end force of 0.25 pounds and a final end force of 2 pounds, making it well-suited for light-duty indexing and locking tasks. The body is constructed from stainless steel with a black finish for corrosion resistance and a clean appearance in service panels and fabricated assemblies.

This plunger is commonly installed in light industrial equipment, HVAC enclosures, electrical panel assemblies, and mechanical fixtures where a hand-adjustable locking mechanism is needed. The locking knob design allows technicians to set and hold plunger position without additional tooling. It is installed by threading into a 3/8-16 tapped hole and is suitable for both production and field-service applications where repeated adjustment is required.

Key Features

• 3/8-16 thread size for standard tapped-hole installation
• Delrin locking knob provides tool-free hand adjustment and positive hold
• Initial end force of 0.25 pounds with final end force of 2 pounds for light-duty indexing
• Stainless steel construction with black finish for corrosion resistance
• Compact body length of 0.94 inches suits space-constrained assemblies
• Plunger projection of 0.18 inches for shallow-engagement applications

Compatibility

Designed as an OEM-style replacement or direct installation component for any assembly using a 3/8-16 tapped hole requiring a locking knob handle plunger with a 0.25-inch maximum plunger diameter.

Installation Notes

Installation is performed by threading the SDKL38-G into a properly tapped 3/8-16 hole by hand or with a suitable wrench on the hex flat. Power down or de-energize any equipment before servicing panels or assemblies where this plunger is being installed or replaced. Do not overtighten the body into the tapped hole, as this may damage the thread engagement or restrict plunger travel. Follow applicable equipment manufacturer guidelines and relevant codes for mechanical fastener installation.
