Yes! Every part of the tool is either covered under warranty or can be purchased separately. We have many commonly needed replacement parts available on our website. Please contact us here or call 760-279-3033 if you are having trouble finding the part you need. Top (large) stop and T-square parts are only available as a set, as they need to be precision-mated in-house to a tolerance of .001” square for us to be able to guarantee their accuracy.
