Quick Release BB Adaptor (upper left in picture) screws into into your buzz bar or bankstick and locks down tight with the knurled nut. The Quick Release Top Cup (top left and included in the Adapter) screws onto the bite alarm or rod rest. The large screw(included in the adapter) or the T-Lock Screw (lower lower) locks the Cup into the Adapter.
A quick quarter turn or so of the screw releases the Cup and a quick turn of the Cup removes it from the buzz bar or bankstick.
