Measure the depth from the back of the stile to the inside wall of the door edge. Equate the distance from
the face of the mounting plate to the end of depth adjusting tube spacers. Use a 3⁄16” (4.76 mm) hex key to
nd tune depth. Hex key size is the same as the one included in the 459 series push pull paddles.
