  • 21 in height fits low-clearance docks

Corner Post for Single Guard Rail Level

This 21 in steel corner post is designed for single guard rail levels on marine docks. It fits the 22DN01 through 22DN04 guard rail models and serves as a structural joint in the railing system. The yellow powder-coated finish provides visible marking on the waterfront.

Bolt-on mounting with four anchor points

The post uses a bolt-on mounting style with an 11 in by 11 in base plate that has four holes of 7/8 in diameter. This pattern distributes load across the deck surface when the rail is under lateral pressure. The fixed geometry keeps the rail alignment stable over time.

Powder-coated steel with rubber caps included

The steel construction weighs 40 lb and carries a powder-coated finish that resists corrosion in marine environments. Rubber caps are supplied to cover the post tops and reduce water ingress. The 4 in by 4 in post profile matches the specified guard rail components.
