New and improved design and sealing capabilities

When you're looking for a new lock, you want to make sure that it's going to deliver on its promises. That's why we've designed the Yale Induro® 4-Point Hinged Door Mortice Lock to be more durable and resistant to the elements than its predecessor, while still maintaining the same level of efficiency and ease of use.

With its new reinforced design, the Yale Induro® 4-Point Hinged Door Mortice Lock is an ideal choice for anyone looking to upgrade their current locks - whether they are seeking increased environmental friendliness or simply want a better-performing product.

    Operation Modes

    • Single point - Latch
      Latching mode operates like a regular passage door, with just the single-point latch in operation. Conventional handle-down retracts latch to open the door, and on door closing, the lock will self-latch without any additional input.
    • 4-Point / Multi-point – Lift bolt and projection bolts/remotes
      Multi-point compression locking is activated manually by lifting the handle.
      Lifting the handle throws the lift bolt and the shoot bolts.
      Pulling the handle down retracts all locking points together in a single operation.

Step 1: Lift the door lever/handle; this will engage locking rods at the top and bottom of the door into the door frame.

Step 2: lock the door with your key; this will engage a throw bolt and secure the latch and rods.
