These are large units that can be either cut into a toilet partition (the panel dividing two toilet stalls), or cut directly into the wall. They may have a napkin disposal unit and toilet seat cover dispenser but will always have two rolls to service one toilet stall. There are also somepartition-mounted units that contain just bath tissue, with two rolls on either side, to service two toilet stalls. The spindles in these units may have been changed from a standard spring-loaded spindle to a theft-resistant spindle that requires a key to loosen.
