Peerless-AV PLCK flat panel ceiling bracket products and components use a 1.5" NPT tube that offers versatility, support, and connection. The 1.5" threaded tube makes it simple to customize each bracket to the needs of your specific application. The PLCK-1 kit combines the PLCM-2 tilt box with a 1.5" NPT fixed-length tube and a 1.5" NPS coupler that allows for easy retrofitting of existing installations. When combined with Peerless-AV's PLP-UNL dedicated or universal display adapter, it offers the perfect choice for upgrading ceiling mounts for flat panel displays in sports spaces, airports, receptions, or retail environments.
