Product description

Securing the sprocket to the safety shaft in a Weaver lift requires a reliable set screw that won't vibrate loose over time. This SVI replacement, matching OEM S-7221, is designed to provide the secondary retention needed to keep the safety mechanism fully integrated. If a set screw fails or goes missing, the sprocket can shift along the shaft, causing chain misalignment and potential safety lock failure. This screw is made from high-strength alloy with precise threading to ensure it bites deeply and stays put. It is a low-cost but high-importance part for maintaining the long-term reliability of your Weaver lift's manual safety system.
