The Patriot Docks 4 ft.x8 ft. Aluminum Gangway Kit is an excellent way to transition from shoreline to pier, especially in fluctuating water. The gangway features all aluminum components with straightforward assembly instructions. The gangway uses 1-1/2 inchx3-1/2 inchx1/8 inch aluminum rectangular tube framing and 1-1/2 inch i.d. aluminum pipe for handrails. The kit includes the gangway frame, decking, handrails for both sides and a hinge for one end of the gangway; optional second hinge or rollers are available for the opposite end of the ramp to suit the application (contact the manufacturer for more details on gangway accessories).
