The RCU Designs Accessory Shelf for the R1200CL is ideal for mounting a radar detector, GPS unit, a garage door opener or whatever you might think of that will mount on the approximate 4” x 10” surface. The shelf is supported directly on top of the dash using two brackets and two spacers that fasten with two screws into existing holes between the windshield and dash lip. Shelf and brackets are machined from aircraft-quality, aluminum alloy. The shelf is painted in black powder coat for an unbelievably tough and long-lasting finish. Struts and brackets are anodized in a black, satin finish. Screws and nuts are black, zinc-plated for corrosion resistance. The shelf can be easily drilled to mount your accessories or many users have found that adhesive-backed, industrial-strength, hook and loop material will satisfy their needs. Of course, there are no holes to drill for installation.
