Gibraltar GLH-568-G Type E Gear Lever Arm 3/8-16 Stem

Product Description

The GIBRALTAR GLH-568-G is a Type E gear lever arm with a cylindrical knob, designed for manual adjustment and positioning applications in industrial and mechanical systems. The arm features a stainless steel shaft measuring 0.375 inches in diameter and 4.92 inches in length, paired with a phenolic cylindrical knob 0.91 inches in diameter and 2.76 inches in length. The 3/8-16 threaded stem provides a secure, standardized connection point with a 0.55-inch thread engagement length. Total handle length is 7.68 inches. This lever arm is installed by machine builders, maintenance technicians, and mechanical assemblers working on equipment that requires repeatable manual control positions.

The GLH-568-G suits industrial machinery, jigs, fixtures, and positioning equipment where a compact, ergonomic lever arm is needed for manual locking or indexing. The 3/8-16 stem thread is a common unified coarse thread size, making this arm compatible with a wide range of standard threaded boss inserts and machine housings. The phenolic knob resists oils, coolants, and moderate heat, making it appropriate for machine tool environments and general industrial shop use.

Installation Notes

Installation is performed by mechanical assemblers or maintenance technicians using standard hand tools. Ensure the mating threaded boss or insert is clean and free of debris before threading the stem in. Do not over-torque the stem into plastic or soft metal housings. Verify that the lever arm sweep path is clear of adjacent components before placing the assembly into service.
