Gibraltar G10-1500AU Pointer Control Knob 1-1/8 in

Product Description

The GIBRALTAR G10-1500AU is a pointer-style control knob designed for use with control shafts requiring a 1/4 x 1/2 inch D-bore hole. It measures 1-1/8 inches in diameter and 9/16 inches in height, with a 1/2 inch hole depth and a center bore of 11/16 inches. Secured by an 8-32 set screw, this knob provides a reliable grip and clear directional indication in panel-mount control applications. The PH-style figure and insert height of 1/2 inch make it suitable for instrumentation and equipment control panels across HVAC, electrical, and industrial service environments.

This knob is used in applications where a pointer indicator is needed to show the position of a rotary control shaft. Typical installations include control panels, thermostats, variable-speed drives, and other equipment requiring clear visual feedback of a shaft position. It is installed by technicians and service professionals working on electrical control assemblies, instrumentation panels, and related mechanical control systems. The compact form factor makes it well suited for both residential and light commercial equipment panels.
