I'm not sure if that's what they're even called. Basically I need something like an engineer's square or L bracket that I can use it for clamping up against on two sides for squareness. If that makes sense?

I'm not convinced about the squareness of the really cheap stuff, and an engineer's square only has one end I can clamp to. The one in the link is unnecessarily expensive.
