With this in mind Wadsworth has designed an adapter with 1/4 wide tongue that will fit most older style sash brackets. Made of cast zinc, the adapter slips easily into the end of the rack arm and is held in place with a clevis pin. ROUND & SQUARE U-BOLTS* To determine size, see the illustration below.
