Made of 3/16" thick clear acrylic, this larger-sized J-shelf tilts 10 degrees, and has a flat bottom, with open ends. Small spacer bars on the back tilt the bottom of j-shelf out from the slatwall. Measures 24" wide, with a 5-1/4" deep pocket from front to back. The front lip is 1-1/4" high, and the back is 6-1/2" high. These shelves are deep enough to display videotapes edge out, as well as many other items.
