Dock Hardware, Wheel Chocks and Drum Accessories

Wheel chocks, anchors and guardrails: sized to the load

Safety hardware is chosen by the load it must hold. A wheel chock must suit the tire and the weight of the vehicle, with a rubber or urethane face for grip, and it is used on the downhill side of the wheel, ideally in pairs. Wedge anchors are specified by diameter and length, and the hole in the concrete must match the anchor diameter. Guardrails and barrier panels list their height and the load rating of the posts and base.

Float drums and drum faucets: buoyancy and compatibility

A float drum is a sealed barrel that supports a dock. A 55-gallon drum displaces roughly 450 lb of water when fully submerged, so each drum should carry much less, to keep the deck well above the waterline. Use sealed, UV-resistant polyethylene drums with tight bungs, and strap them in place rather than drilling through them. Drum faucets must match the bung opening and the liquid: brass suits many fluids, self-closing designs reduce spills, and corrosive chemicals need compatible materials.

Questions about Dock Hardware, Wheel Chocks and Drum Accessories

What size wheel chock do I need?

Pick a chock rated for the vehicle's weight and tall enough to stop the tire climbing over it, usually at least about a quarter of the tire's height. Set it firmly against the tread on the downhill side, and use a pair when possible.

How many float drums does a dock need?

Work from the weight of the deck, people and gear, then divide by the usable buoyancy of one drum, which is well below its full displacement. Add drums for a safety margin, space them evenly and make sure each one is sealed.

How do I fit a wedge anchor?

Drill the hole to the anchor's diameter and at least the stated depth, clear out the dust, insert the anchor through the fixture and tighten the nut to the stated torque so the wedge clip expands. Use anchors rated for the base material.
