Inquiry (采购产品): Release a Seat II I have purchased model 5498-L and would like to know if the retainer bracket must be used or not. If installed, then the seat is not removable. It appears that the mounting plate just slides directly on the surface of the boat seat, does this scratch or wear the finish? **** Hidden Message ***** frank distefano 1 sunset Plaza kalispell, MT 59901 USA Company: architects design group, pc Phone: 406-257-7125 E-mail: fjdistefano@architects-design-group.com **** Hidden Message ***** fjdistefano@architects-design-group.com
