Jainson Lock Stainless Steel and Aluminium PEAK Long Mortise Lock Set with 3 Keys

Mortise locksets are designed for doors using mortise locks, where a box lock is installed into a deep pocket or “mortise” in the edge of the door. Mortise lock sets are available in a variety of classic designs and include backplate, door knob, box lock and all the hardware you need.

• A mortise lock has several benefits over other types of locksets:
• They can be used on many different types of doors, including hollow core, solid core and fire rated doors.
• They’re easy to install with simple tools.
• They have a long life span because they don't require replacement parts like cylindrical locks do.
• Mortise locksets also have some disadvantages:

The door must be drilled in order to install them properly so it can take longer than other types of locksets to install them; however, most companies will drill your new door for free if it's purchased through them.

Mortise locksets are more expensive than other types of locksets because they require more materials and labor to build; however, they're still less expensive than custom made doors that come standard with mortise locks already installed in them
