Product Information

Full details

The TIMCO Bathroom Door Lock is a robust, medium-duty mortice lock designed for homeowners and contractors seeking a secure, reliable privacy solution for internal timber doors. Its key benefit is the combination of a smooth-operating latch and a secure 5mm spindle thumbturn mechanism, making it ideal for bathroom and en-suite privacy. However, users should note that it is specifically designed for use with sprung door handles and requires a mortice cut-out suitable for its 78mm case depth.

Extended Product Information

FAQs

Does this lock come with a handle?

No, this product is the mortice lock mechanism only. Handles and thumbturns must be purchased separately.

Is this lock suitable for external doors?

No, this is a medium-duty internal mortice lock and is not designed for external security requirements.

What size spindle does the thumbturn require?

The bathroom follower requires a standard 5mm spindle.

Can this be used on a fire door?

Yes, this lock is Certifire approved for 30 and 60-minute fire-rated timber doors.

What is the backset of this lock?

The backset is 57mm.

Does the finish require special maintenance?

The bronze finish is durable but should be cleaned with a soft, dry cloth; avoid abrasive cleaners or solvent-based sprays.

Troubleshooting

The latch is stuck or not returning fully

Ensure the handle is a sprung model. If it is already sprung, check that the mortice is not too tight and causing friction on the lock case.

The thumbturn is difficult to operate

Check that the 5mm spindle is not too long or binding against the opposite side of the door furniture.

The latch is facing the wrong direction

Remove the lock from the door, locate the latch reversal screw or mechanism on the side of the lock, rotate the latch head, and replace.

Pros and Cons

Pros

  • Versatile handedness allows for easy installation on any door
  • Certified for use on fire doors
  • High-quality bronze-style aesthetic
  • Smooth operation for daily bathroom use

Cons

  • Requires professional mortice installation skills
  • Requires specifically sprung door handles for optimal performance
  • Not intended for high-security exterior door applications

Setup, Compatibility & Care

To install this lock, you will need to mortice the door edge to accept the 78mm case depth. Ensure your door thickness is appropriate for the mortice width. The lock is compatible with any standard bathroom thumbturn set that uses a 5mm spindle.

  • Compatibility: Best paired with sprung lever handles. Ensure your door frame can accommodate the included strike plate.
  • Installation: Use a sharp chisel to clean the mortice recess, ensuring the forend plate sits flush with the door edge.
  • Care: Periodically check that screws are tightened. If the latch becomes stiff, a small amount of light maintenance lubricant can be applied to the latch bolt. Avoid harsh chemical cleaners on the bronze finish; a dry or slightly damp microfiber cloth is sufficient for cleaning.
