Construction Plans for a Custom Designed Low (Mini) Tunnel

Proceed with the tunnel assembly by installing the hoops. Insert one end of the hoop into a receptacle and the other end of the hoop into the receptacle directly opposite on the other side of the bed. When installed correctly, the hoop ends should rest against the screws used to secure the receptacles to the sides of the beds.

To prevent excess bending of the end hoops when the cover is applied, use a piece of rope to connect the top of the hoops to the ends of the beds. If you're covering a rubber lumber bed, fasten the rope to an eye screw inserted into the rubber at each end of the bed. If you're covering a corrugated sheet metal bed, tie the rope to the sucker rod stakes at each end of the bed.
