Gibraltar PKG-382-G Lobed Knob 40mm 7-point M8x1.25 Tpe

Product Description

The GIBRALTAR PKG-382-G is a 7-point lobed knob designed for manual adjustment applications in industrial, mechanical, and trade equipment. Built from thermoplastic elastomer (TPE), the knob provides a firm, grippy surface that resists slipping during hand-tightening. The head diameter measures 40 mm (approximately 1.57 inches) and the overall height is 25 mm (approximately 0.98 inches). The threaded steel stem is M8 x 1.25, with a 40 mm (approximately 1.57 inches) thread length, making it suitable for secure fastening into standard M8-tapped components. This type of knob is commonly installed by HVAC technicians, equipment assemblers, and maintenance professionals who need tool-free panel, cover, or access-door fastening.

The PKG-382-G is well-suited for use on equipment panels, control enclosures, inspection covers, and adjustment mechanisms across residential and light commercial applications. The M8 x 1.25 threaded stem fits standard M8 tapped holes found on a wide range of HVAC cabinets, electrical enclosures, and mechanical assemblies. The TPE construction makes the knob appropriate for both indoor and light-duty outdoor environments where a comfortable, non-slip grip is required. It ships as a single-piece unit.

Installation Notes

Installation is performed by hand or with light tooling into any M8 x 1.25 tapped hole. Confirm the thread depth of the receiving hole is sufficient for the 40 mm stem length before installation. Power down and de-energize any electrical equipment before removing or replacing access panel hardware. Do not overtighten TPE-bodied knobs, as excessive torque can strip the stem or deform the base.
