This pair of lightweight and sturdy stays is designed for medium to large Bahama or Bermuda shutters and made out of aluminum to avoid rust. This set comes with brass pins for attaching the rod to the brackets when the shutter is held open. When the shutter is to be closed during a storm the rods can be removed and the brackets locked together to keep the shutter fastened. The bars can also be cut to smaller lengths if desired. Optional sill mount brackets are included with this set. The stay rods measure 15/16" in diameter and the brackets are 3 9/16" long by 1 3/16" in width and project 1 1/2".
