Our U-Shaped Flush Mount allows you to mount panel to panel flush if needed. Will also allow you allow adjust up to 1" away giving you a lot of adjustment. 
NOTE: Mounting holes on top only allow this bracket to be pop riveted into a bracket with a spacing of 1.375" from center of pop rivet hole to center of pop rivet hole. If you are planning to use your existing dzus brackets make sure you have this spacing to mount to. 
If not we also sell brackets to accommodate this as well as dzus rails.
