Gibraltar G10-0698-D Fluted Tapered Knob Phenolic Self-fixing

Product Description

The GIBRALTAR G10-0698-D is a fluted tapered knob made from phenolic material, designed for use on shafts, rods, and threaded or smooth-bore control stems found in HVAC equipment panels, electrical enclosures, and industrial machinery. The knob accepts a 0.5 inch bore with a 2.5 inch deep hole, allowing it to seat securely over a range of shaft lengths. Overall length is 4.375 inches, with a 1 inch base diameter and a 1.375 inch head diameter. The self-fixing hole mount eliminates the need for a set screw by gripping the shaft through a tapered interference fit. Finished in black phenolic for resistance to heat and common shop fluids.

This knob is suited for manual control applications in residential and light commercial HVAC systems, electrical panel assemblies, pump control stations, and general-purpose equipment where a reliable, tool-free knob replacement is needed. The fluted profile provides positive grip even with oily or gloved hands, making it a practical choice for service technicians replacing worn or broken knobs on control shafts and variable-speed or manual-override assemblies.

Key Features

• Self-fixing hole mount grips shaft without a set screw for quick installation
• 0.5 inch bore diameter with 2.5 inch deep hole accommodates a range of shaft lengths
• Fluted tapered exterior improves hand grip in wet or gloved conditions

Compatibility

Designed as an OEM-style replacement knob for control shafts and manual-adjust stems in HVAC equipment panels, electrical enclosures, and general industrial machinery where a 0.5 inch bore self-fixing knob is required.

Installation Notes

Installation does not require special tools — the self-fixing taper grips the shaft when pressed firmly into place. De-energize or power down any equipment before replacing a control knob to prevent accidental activation. Verify shaft diameter and length against the 0.5 inch bore and 2.5 inch depth before installation to confirm proper fit. Removal typically requires a flat-blade tool or knob puller to disengage the tapered grip without damaging the shaft.
