All NOMAR corner units are pre-notched to help conform around the end of the docks. There is a right side and a left side of these units. To tell them apart the thermal cut side goes down and the larger end goes on the inside of the slip.

Before mounting pre-bend the bumper to locate the notched area and help with locating the unit on the dock.

Start with the small side first, mounting it to the dock, allowing the notched area to be at the corner of the dock. Then form the bumper around the corner and finish mounting. Place screws approximately 2 to 3 inches apart on the top and bottom of the unit.
