Product Overview

The SL-100B is a black Shaft Lock made of nylon body, brass per QQ-B-626 nickel plated per QQ-N-290, class-1, type-V insert. The shaft lock prevents control shafts from rotating under conditions of shock, vibration or accidental contact. It forms a dust and waterproof seal at the shaft and also at the panel surface. It features simple, effective and inexpensive. The shaft lock with tapered nylon collar grips the control shaft tightly forming a dust and water-tight seal and exerting an even frictional drag which resists accidental rotation. A molded lip at the outer edge of the base compresses against the panel surface to complete the sealing function of the device. To adjust the control smoothly and accurately, merely insert to screwdriver and turn - no unlocking and relocking required. Shaft lock mounts directly to the threaded bushings found on most potentiometers and other variable controls.
  • Water and dust seal at shaft and panel
