Product Information

Full details

The Union 3 Lever Mortice Sashlock is an ideal security solution for residential timber doors up to 54mm thick, offering robust protection through its integrated anti-saw brass deadbolt. Perfect for homeowners looking for reliable door hardware that supports both left and right-hinged configurations, this lock provides ease of use with its dual-action handle and key operation. While it provides solid everyday security for internal or non-critical external doors, users should note that it is designed specifically for timber applications and may not be suitable for high-security exterior requirements.

Troubleshooting

Key is difficult to turn

Check if the door is slightly misaligned with the strike plate. Adjust the strike plate position so the deadbolt enters the hole without friction.

Latch bolt does not retract fully

Ensure the handle mechanism is correctly aligned with the follower and that the spring has not been obstructed by debris inside the mortice pocket.

Pros and Cons

Pros

  • Durable satin chrome finish
  • Anti-saw deadbolt technology
  • Suitable for both door handing types
  • Standardized 65mm case size for easy replacement
  • Includes two nickel-plated steel keys

Cons

  • Not intended for high-security external door needs
  • Limited to timber doors up to 54mm thick
  • Requires professional morticing tools for new installations

Setup, Compatibility & Care

Installation requires a mortice chisel and a drill to create the pocket in the door edge. Ensure your timber door does not exceed 54mm in thickness to guarantee the lock sits flush. When installing, confirm that the backset of 44.5mm aligns with your door handle position.

For maintenance, avoid using harsh chemical cleaners on the satin chrome finish; a soft, damp cloth is sufficient to keep the surface clean. If the key operation becomes stiff over time, applying a small amount of dry graphite lubricant into the keyhole can restore smooth performance. Do not use oil-based lubricants, as these can attract dust and grime into the lever mechanism.
