Extreme Max's Dock Post Bracket Kit is designed to allow the addition of 2 additional legs to your existing dock, helping provide greater dock stability. The post brackets attach to the dock's faceboard and utilize 2 mounting plates for each bracket, 1 on each side of the faceboard, giving each new leg a solid connection to the dock. The 5 in. x 5 in. mounting plates cover a large surface area, while 4 pre-drilled mounting holes on each plate allow ease of positioning and alignment. The post brackets accept dock legs up to 1-7/8 in. Dia and include 2 threaded bolt holes on each bracket to lock the legs into place. The heavy-duty steel construction provides exceptional strength, while the galvanized finish resists rust and corrosion in freshwater marine environments. Each kit includes 2 post brackets, 4 mounting plates, and 4 hex head screws for locking the legs. Due to the variety of surfaces to which the brackets may be applied, mounting hardware is not included.
