Product Information

Full details

The Union 2277 3 Lever Mortice Sashlock is an ideal security solution for internal timber doors that require a reliable latching and locking mechanism. Perfect for homeowners or DIYers looking to secure rooms within a home, it offers a sturdy deadbolt and convenient lever-handle operation; however, it is not suitable for high-security external door applications due to its 3-lever design.

FAQs

Can I use this lock on an external door?

This is a 3-lever lock designed primarily for internal timber doors. It is not recommended for external doors where higher security standards are required.

Is this lock suitable for a 35mm thick door?

Yes, it is suitable for timber doors up to 54mm thick, making it compatible with standard 35mm to 45mm internal doors.

Does this lock come with everything needed for installation?

The kit includes the sashlock unit and two steel nickel-plated keys. Door furniture (handles) and mounting screws must be purchased separately.

How do I change the handing for a different door swing?

The latch is designed to be easily reversible; refer to the included manual to see how to extract and rotate the latch bolt head.

How many keys are provided?

The package includes two steel nickel-plated keys.

Troubleshooting

Key is difficult to turn

Ensure the door is not warped and the strike plate is correctly aligned. Apply a small amount of graphite lubricant to the key and insert it several times.

Latch does not retract fully

Check that the door furniture (handles) is correctly installed and not binding against the door surface. Ensure the spindle is the correct length.

Deadbolt strikes the frame

Adjust the position of the striking plate on the door frame to ensure the deadbolt enters the hole cleanly without obstruction.

Pros and Cons

Pros

  • Compatible with both left and right-hinged doors
  • Anti-saw deadbolt provides enhanced strength
  • Easy operation with standard lever handles
  • Supports modern bolt-through door furniture

Cons

  • 3-lever mechanism offers lower security than 5-lever alternatives
  • Not intended for high-security external door use
  • Limited to door thicknesses up to 54mm

Setup, Compatibility & Care

This mortice sashlock is designed for timber doors with a maximum thickness of 54mm. Before installation, ensure the door is properly prepared for a mortice cutout. The lock is reversible, meaning you can swap the latch direction to suit your door swing without additional tools. For maintenance, it is recommended to keep the internal mechanism clear of debris. If the key operation becomes stiff over time, a light application of a graphite-based lubricant into the keyway can improve movement; avoid using oil-based sprays which can attract dust.
