Grand Pacific docking wheels are made from composite EVA foam coated in polyester giving them great shock absorbing properties and improved life expectancy. The solid foam wheel cannot deflate or get punctured and rotates freely around the galvanised steel bracket which is mounted to the top of the dock.
To install the dock wheel: unscrew the top cap and remove the wheel from the post. Fasten the base plate to the dock in your chosen position. Reinstall the wheel back on the post and screw the cap back on to keep the wheel in place.
