Product description

Small but indispensable, the safety system key is what locks the sprocket to the drive shaft on Weaver manual ratchet assemblies. This SVI part (OEM 7389) is sized at 3/16" x 3/4" to provide a perfect fit in the shaft and sprocket keyways. Without a properly sized and undamaged key, the sprocket would simply spin on the shaft, rendering the safety mechanism inoperable. Over time, these keys can shear or become deformed due to mechanical stress or improper maintenance. This replacement key is made from high-strength steel to ensure that all rotational force from the operator is accurately transferred to the safety locks. It is an essential item to have on hand whenever servicing the safety ratchet system.
