Peerless-AV's PLCK flat panel ceiling mount products and components utilize a 1.5" NPT pipe for versatility, support and connection. The 1.5" NPT threaded pipe make it simple to customize each mount to your specific application. The PLCK-1 kit combines the PLCM-2 tilt box, fixed length 1.5" NPT column and 1.5' NPS coupler to easily retrofit exiting installations. When combined with Peerless-AV's PLP-UNL universal or dedicated display adaptor, it provides the perfect combination for retrofitting flat panel ceiling mounts in sports facilities, airports, lobbies or retail environments.
