Gibraltar G10-2837-F Lobed Knob 4-point Thermoplastic

Product Description

The GIBRALTAR G10-2837-F is a 4-point lobed knob designed for hand-tightening and manual adjustment applications in industrial, mechanical, and trade equipment. Constructed from thermoplastic elastomer (TPE), it provides a firm yet comfortable grip surface without requiring tools. The knob features a 2.25-inch head diameter and accepts a 1/4-20 threaded fastener with a 0.5-inch thread engagement depth, making it a standard fit for a wide range of clamping, positioning, and panel-mounting tasks. Machinists, equipment technicians, and general maintenance professionals install this type of knob wherever repeatable hand-tightened adjustments are needed.

This lobed knob is suited for use on jigs, fixtures, machine guards, enclosure panels, and equipment frames in both industrial and light commercial environments. The 4-lobe profile distributes hand force evenly across the grip, reducing fatigue during frequent adjustments. The black TPE construction resists oils and common shop chemicals, making it appropriate for production floor and service bay installations where hardware sees regular handling.

Key Features

• 4-point lobe profile for ergonomic hand-tightening without tools
• 2.25-inch head diameter for confident grip surface area
• Thermoplastic elastomer construction resists oils and common shop fluids
• 1/4-20 threaded hole with 0.5-inch thread depth for standard fastener compatibility
• 1-inch hub diameter and 1-inch overall height for compact installation clearance
• Black finish suitable for general industrial and mechanical applications

Compatibility

Designed as an OEM-style replacement or original-install lobed knob for equipment, fixtures, and panels using 1/4-20 threaded hardware.

Installation Notes

Installation requires no special tools — thread the knob onto a 1/4-20 stud or bolt by hand to the required engagement depth. Ensure the mating thread is clean and free of debris before installation. Do not exceed hand-tight torque; using a wrench or pliers on a lobed knob can crack the hub. Verify thread depth engagement does not bottom out the fastener before the knob seats properly against the mounting surface.
