The Cal-Royal Hotel Privacy Door Lock (HPDL) is recommended for use in environments with corridor to room openings such as hotels, dormitories, apartments and even private residences. The latch would allow the door to be partially opened for identification while providing privacy and security for the resident. The HPDL in the open position, cannot be used to hold the door open. The silicone pads (6) provides additional protection for the door and act as a silencer.

The HPDL is UL Classified as a fire door accessory. It also meets the requirements of NFPA that requires auxillary hardware to not interfere or prohibit the proper operation of fire doors, and that doors are not blocked or wedged in the open position. An optional Rivet Nut can be applied for a more secure and rigid installation.
