The Protege Cartridge Mortise Wireless Lock is an ANSI Grade 1 Mortise lock – with or without a deadbolt – and is rated for over 12 million cycles.
The ‘Mortise’ is the rectangular pocket cutout of the door that the lock body fits into. Above this is a second pocket cutout that fits the ‘Cartridge’, which includes the batteries and the electronics. With the electronics hidden inside the door, the Cartridge Mortise is refined and modern while also providing a world-leading apartment security and access control solution.
