The PDS-PLUS-W is a low-profile universal projector mount that can be mounted directly to the ceiling or in use with a drop pipe. This mount truly is universal because it features a slotted mounting base with six interchangeable legs ( four long and two short) to reach both shorter and wider mounting points. Most standard sized projectors will work well with the PDS-PLUS-W. Installation of the PDS-PLUS-W is easy because it mates to standard 1.5 in. NPT pipe, or directly to structural surfaces. In addition, it is very lightweight, weighing under 5lbs, in order to make ceiling installation a little easier on installers. Being one of the most popular mounts for education applications, the PDS-PLUS-W is OSHPD approved, UL listed and includes Lock-ItT security hardware so you have piece of mind when installing in classrooms or high traffic areas.
