Piper Tail Brace Wire Adjustment
Max length is determined by at least 3 threads of the wire protruding through the U41051-000 brass nipple.
Minimum length is determined by the threads bottoming out in the U41051-000 nipple or just short of contact with the clevis; whichever comes first.
U10555-002 (Long Wire):
Max length is approximately 43.50” from center to center of the clevis holes.
Or 41.25” from the outside surface to outside surface of the nipple flange.
Min. length is approximately 42.75” from center to center of the clevis holes.
Or 40.50” from the outside surface to outside surface of the nipple flange.
This allows approximately .75” (3/4”) adjustment from maximum to minimum length.
U10556-002 (Short Wire):
Max length is approximately 37.25” from center to center of the clevis holes.
Or 34.75” from the outside surface to outside surface of the nipple flange.
Min. length is approximately 36.375” from center to center of the clevis holes.
Or 33.875” from the outside surface to outside surface of the nipple flange.
This allows approximately .875” (7/8”) adjustment from maximum to minimum length.
Upon installation, when the fittings are tightened all four wires should produce a similar “low” musical tone.
