Product Information

Full details

The Yale Locks M888 Tubular Mortice Latch is an ideal solution for homeowners and DIY enthusiasts looking to secure internal doors that do not require a locking mechanism. Designed for smooth, daily operation, this latch provides a reliable way to keep doors closed using a sprung lever handle. While it offers excellent durability and a classic gold finish, it is important to note that this unit is strictly incompatible with unsprung lever handles, requiring a compatible sprung set for proper functionality.

FAQs

Does this latch come with a locking mechanism?

No, the M888 is a tubular mortice latch designed specifically for passage doors where no locking function is required.

Can I use this with any door handle?

You must use this latch with sprung lever handles only. It will not function correctly with unsprung handles.

What is the primary benefit of the tubular design?

The tubular design allows for a circular bore hole installation, which is significantly faster and easier than the rectangular morticing required for traditional latches.

Is this suitable for external doors?

No, this is intended for internal doors only and does not provide security locking features.

How do I maintain the gold finish?

Clean with a soft, damp cloth. Avoid harsh chemical cleaners or abrasive materials that could strip the finish.

Troubleshooting

The handle remains in the downward position after use.

Your handle is likely unsprung. Replace the handle with a sprung lever handle or install an additional heavy-duty spring cassette.

The latch is difficult to close or requires force.

Check the alignment of the strike plate on the door frame. If the latch bolt is hitting the frame edge, adjust the strike plate slightly.

Pros and Cons

Pros

  • Quick and straightforward installation process
  • High-quality construction from a reputable brand
  • Smooth and quiet bolt retraction
  • Attractive gold finish for aesthetic consistency

Cons

  • Limited to non-locking internal door applications
  • Color may vary slightly from online representations

Setup, Compatibility & Care

To ensure optimal performance, verify that your door thickness is compatible with the standard mortice sizing before installation.

  1. Compatibility Check: Ensure your selected door handles are of the *sprung* variety. If your handles are unsprung, the latch bolt will not return to the neutral position, causing the door to hang slightly open.
  2. Installation: Bore the required hole in the door edge based on the latch specifications. Insert the unit, ensuring the bolt bevel faces the direction of the door closing.
  3. Care: Keep the moving parts free of debris. If the latch becomes stiff over time, a light application of a silicone-based lubricant on the bolt can restore smooth operation. Avoid using heavy greases that may attract dust and grit.
