These are a very versatile brochure display system. The Lit Loc’s modular design allows multiple brochure holders to be mounted together side by side and/or front to back. To add additional support for displays with four or more rows, it is recommended that the small Base Clip is attached to the back of the 4th level to space the brochure holders out from the wall. A5 and DL sizes are also available as well as matching accessories.
