Vestil Economical Safety Swing Gates protect people from dock falls. Durable railings are constructed from schedule 10 pipe (1-5/8" O.D.). Units have a top rail height of 46-1/4" and a 25" mid-rail. 4" poly-on-poly wheel allows units to be swung out of the way. The foot release lock keeps the railing from being moved when in use. A single cast socket is included. A baked-in powder-coated yellow finish for toughness.
