Product Information

Full details

The Betley Butterfly Bathroom Mortice Lock is an essential security solution for homeowners and professionals looking for a reliable, modern locking mechanism for interior bathroom doors. This lock provides a smooth, secure operation for residential or commercial settings and features a versatile, reversible latch bolt that fits most standard door configurations. While it offers excellent durability and a sleek aesthetic, users should verify their existing door mortice dimensions before installation to ensure the 57mm backset and 64mm total case size are appropriate for their specific door frame.

FAQs

Is this lock suitable for exterior doors?

No, this is a bathroom mortice sashlock designed for interior privacy and should not be used as the primary security lock for external doors.

Can I flip the latch bolt myself?

Yes, the latch bolt is designed to be reversible to accommodate both left-handed and right-handed door swings.

Does it come with a handle or thumb-turn?

This package includes the mortice lock, strike plate, and screws. Handles and thumb-turn sets must be purchased separately.

What is the backset dimension?

The backset for this lock is 57mm.

Will the black finish scratch easily?

The coating is durable for standard use, but avoid using abrasive pads or harsh chemicals that can wear away the finish over time.

Troubleshooting

The latch bolt does not align with the strike plate

Adjust the strike plate position slightly on the door frame until the latch enters the cavity smoothly.

The door handle is stiff or sticks

Check that the door is not warped and ensure the internal screws are not overtightened, which can bind the spindle.

The lock does not fit the existing hole

Measure your current door mortice to confirm it meets the 64mm standard; you may need to chisel the wood slightly if the cavity is undersized.

Pros and Cons

Pros

  • Reversible latch mechanism fits any door hand
  • Stylish black finish suits modern interiors
  • Includes all necessary installation hardware
  • Durable build quality for frequent daily use

Cons

  • Requires specific mortice measurements for installation
  • Only available in a black finish
  • Not suitable for exterior doors requiring high-security deadbolts

Setup, Compatibility & Care

To install this lock, start by ensuring your door mortice cut-out matches the 64mm standard size. Slide the lock case into the cavity and secure it using the provided screws through the forend. Once the lock is seated, attach the strike plate to the door frame, aligning it perfectly with the latch bolt for a smooth closing action.

For ongoing care, avoid using harsh chemical cleaners on the black coating. Instead, wipe the surface with a soft, damp cloth. If the mechanism becomes stiff over time, a small application of silicone-based lubricant inside the latch cavity can restore its smooth function.
