Add the beauty of carmelized bamboo and the functionality of 1100+ square inches of storage surface.  The Bed Riser Tops will fasten to the bed risers using velcro, mating with the velcro that comes on the bed riser frame.
 
The Bed Riser Tops are made to fit the contours of the Revel pop-outs, custom made to fit the driver and passenger side dimensions.  
 
The Driver Side is wider, with an overall dimension of 51.625" long and 13" wide.  The Passenger side is more narrow to mate with the smaller pop-out, with an overall dimension of 51.625" long and 10.5" wide.  
 
When installing, some users find the adhesive backed velcro works well to attach to the bed riser frame.  Other users have predrilled holes through their bed riser and drive screw up through the aluminum frame into the bottom of the Bed Riser Tops.  Fasteners are not included in the purchase.
