Gibraltar C7-50B-G Revolving Crank Handle Square Bore

Product Description

The GIBRALTAR C7-50B-G is a revolving crank handle designed for manual adjustment and actuation applications in industrial and mechanical settings. Built with a plastic grip and aluminum construction, this handle delivers a lightweight yet durable solution for rotating shafts and threaded stems. The square bore measures 0.625 inches, providing a secure, non-slip engagement with compatible square shafts. The stem length of 1.34 inches suits standard mounting depths found in machinery panels, jigs, fixtures, and equipment enclosures. Installation is straightforward and typically requires no special tooling. This handle is suited for maintenance technicians and machine operators who need a reliable, ergonomic grip for frequent manual adjustments.

The C7-50B-G is intended for use on machine tools, industrial equipment panels, and mechanical fixtures where a revolving grip style improves operator comfort and reduces fatigue during repeated turning tasks. The revolving handle design allows the grip to spin freely relative to the arm, minimizing friction and wrist strain during operation. This makes it a practical choice for applications requiring sustained or repetitive manual actuation.

Installation Notes

Installation is performed by maintenance technicians or machine operators. De-energize or lock out the equipment before mounting or replacing the handle in accordance with applicable LOTO (lockout/tagout) procedures. Ensure the square shaft is clean and free of burrs before seating the bore. Do not force the handle onto an oversized or damaged shaft, as this may compromise fit and function.
