Our fold-over clip has a longer tab on one fastening leg. This Darrel Ralph clip design, stops the lock bar from over bending when you unlock the blade. Our lock stops were designed to be a fail-safe option for your lock-bar on frame-locking knives. This is important to the long term performance of the knife if you decide to carry the knife with the clip positioned for "tip-up" carry or with no clip at all! Just replace the clip with the lock-stop tab.
The hole pattern is exactly the same as the hole pattern on our fold-over clip to make a great standard parts set for your knives.
