The 38mm/BT60 BT Bay Template is used to mark holes on body tubes to align with a coupler tube bay or other parts. There are three equally spaced holes around the perimeter (120 degrees intervals). There is also an alignment mark and a hole that marks the placement of an arming screw that is used in the 38mm bays (the BT60 bays use one of the equally spaced holes for the arming screw).
