GS-AB. Adapter BracketCan be used on any Gullsweep mount to adjust the centre mounting pin to a vertical position. 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 centre pin position. Measures 3/4'' x 2''x1/16''. (made from stainless steel)Part number: GS-AB.
