To be used on any Gullsweep mounting to adjust the center mounting pin to a vertical position. Quick to implement. Especially helpful on the standard permanent GS-4 mounting block. Decks normally may have a pitch of some sort so water runs off, thus a mounting pin directly screwed into the block would not be vertical. The GS-AB bracket is designed so it can be easily bent to achieve a vertical center pin position. Made from stainless steel it measures 3/4” x 2”x1/16”. Pin shown in image not included as bracket uses the standard pin included with your Gullsweep. Postage for this item is £3.50 UK only.
