FAQs

Can this be used on an external door?

No, this is specifically designed for internal doors and does not provide the security features required for exterior use.

Does this latch come with a locking function?

No, this is a tubular latch for passage doors only. It does not include a key or privacy locking mechanism.

What tools are needed for installation?

You will need a drill, drill bits (including a spade bit for the tubular hole), a hammer, and a sharp wood chisel.

Is the strike plate included?

Yes, every unit comes with a matching strike plate and the necessary fixing screws.

How do I maintain the finish?

Clean with a soft, dry cloth. Avoid abrasive cleaners to keep the silver finish looking its best.

Troubleshooting

The door is not staying closed.

Verify that the strike plate is aligned correctly with the latch bolt. You may need to slightly adjust the position of the strike plate on the door frame.

The handle feels stiff or sticks.

Check that the spindle is not binding in the latch mechanism. Ensure the screws holding the latch in place are not over-tightened, which can warp the casing.

Latch bolt does not retract fully.

Inspect the mortice cavity for wood debris or loose splinters that may be obstructing the tubular mechanism.

Pros and Cons

Pros

  • Simple and straightforward installation process
  • Provides a positive, secure-feeling close
  • Compact form factor preserves door integrity
  • High-quality build ensures long-term durability

Cons

  • Designed exclusively for internal door use
  • Requires precision morticing for flush fitting
  • Does not include a lock mechanism (latch only)

Setup, Compatibility & Care

To install, measure the backset required by your handle set and drill the appropriate hole in the edge of the door. Use a chisel to create a shallow rebate so the faceplate sits flush with the wood surface. Secure the latch with the provided screws and align the strike plate on the door frame.

Compatibility: Suitable for most standard internal passage doors. Check that your door thickness accommodates the tubular casing depth.

Care: To maintain smooth operation, avoid using heavy chemical cleaners that could damage the silver finish. A light machine oil or silicone-based lubricant can be applied to the bolt head if the action becomes stiff over time.
