Swing Jaw Corner Clamp

My cage-building project (more on that on near-future posts) is going to much easier with this right-angle clamp, holding the frame securely while a pair of wood screws will be used to complete the deal.  This model also called "swing jaw", which means the two pieces of wood do not need to be the same thickness.  There are other models that include features I didn't need, but look around before buying to see what works best for you.
