Gibraltar G10-2825-A Lobed Knob 4-point Black Tpe

Product Description

The GIBRALTAR G10-2825-A is a 4-point lobed knob designed for manual adjustment and clamping applications in industrial, HVAC, and mechanical assembly environments. Molded from thermoplastic elastomer (TPE), it delivers a firm yet comfortable grip for repeated hand-tightening without tools. The knob features a 5/16-18 threaded hole with a 1/2 inch thread depth, a 1-3/4 inch head diameter, and an overall height of 1 inch. The 3/4 inch hub diameter provides a solid bearing surface. Installers and technicians use this style of knob on access panels, equipment guards, jigs, fixtures, and adjustable mounting assemblies where quick-release or frequent repositioning is required.

This lobed knob is suited for light-duty manual fastening on HVAC equipment panels, electrical enclosures, mechanical fixtures, and general trade equipment. The black TPE construction resists oils, mild solvents, and typical shop-environment contaminants. The 4-lobe profile distributes hand torque evenly, making it practical in confined spaces where a full hand grip is not always possible. It is typically specified by HVAC technicians, electricians, and mechanical assemblers as a replacement or upgrade for slotted or hex fasteners on service panels.

Key Features

• 4-point lobed profile for comfortable hand-tightening without tools
• Thermoplastic elastomer (TPE) construction for grip, durability, and chemical resistance
• 5/16-18 threaded hole with 1/2 inch thread depth for standard fastener compatibility
• 1-3/4 inch head diameter with 3/4 inch hub diameter for broad bearing surface
• 1 inch overall height — compact profile for panels and enclosures with limited clearance
• Black finish suitable for industrial and equipment applications

Compatibility

Designed as a standard 5/16-18 threaded lobed knob for use on HVAC access panels, electrical enclosures, mechanical fixtures, jigs, and adjustable assemblies requiring tool-free manual fastening.

Installation Notes

Installation requires no special tools — thread the knob onto a 5/16-18 stud or bolt by hand and tighten to snug fit. Ensure the mating stud thread length does not exceed the 1/2 inch hole depth to avoid bottoming out and stripping the insert. Always de-energize or shut down equipment before servicing panels or guards where this knob is used as a fastener. Follow applicable equipment manufacturer guidelines for access panel fastener torque limits.
