The SmartMount^® PLCM-1 Ceiling Mounts utilize 1.5" NPT extension pipes for versatility, support, and connection. The 1.5" NPT threaded pipes make it simple to customize each mount to your specific application. The PLCM-1 kit combines the PLCM-2 tilt box and an EXT13 fixed length 1.5" NPT column, to deliver a drop of 36", -5°/ 2° of adjustable tilt and 36° of swivel. When combined with a Peerless-AV® ceiling plate, and a universal or fixed display adaptor plate, it creates the perfect combination for flat panel ceiling mounting in sports facilities, airports, lobbies, or retail environments.
