Full details
The Carlisle Brass Bolt-Through Tubular Latch is designed for homeowners and contractors seeking a reliable and straightforward hardware solution for internal door installations. Its primary benefit lies in its bolt-through construction, which provides enhanced stability for door furniture and ensures consistent, smooth latching performance. While it is an excellent choice for standard internal doors, users should ensure their door thickness and handle type are compatible with the 64mm length to avoid improper fitting.

FAQs
What does the 64mm dimension represent?
The 64mm dimension refers to the latch length, specifically the distance from the edge of the door to the center of the spindle hole.
Can I use this with any door handle?
It is optimized for handles with bolt-through fixings, but it can also be used with standard handles. Ensure your handle set allows for bolt-through installation if you wish to take full advantage of this feature.
Is this suitable for fire doors?
Please check the certification markings on the specific product packaging. Tubular latches for fire doors must meet specific fire safety standards.
How do I lubricate the latch?
Use a small amount of dry PTFE spray or graphite powder. Avoid standard household oils as they can collect grit.
Is this a bathroom or bedroom latch?
This is a standard tubular latch. It does not contain a locking mechanism for privacy; it is designed only to keep the door shut.
Troubleshooting
Latch is sticking or failing to retract
Check that the door is correctly aligned in the frame and that no debris is inside the strike plate. Ensure the latch is not being pinched by tight mortise work.
Handles feel loose even after installation
Verify that the bolt-through screws are fully tightened and properly connected through the latch's dedicated mounting holes.
Door does not latch securely
Check the alignment of the latch bolt with the strike plate on the door frame. Adjust the strike plate position if necessary to ensure the bolt sits flush when closed.

Setup, Compatibility & Care
To install this latch, you will need to drill a standard hole in the edge of the door to accommodate the latch body, along with a secondary hole for the spindle and bolt-through fixings. Ensure that the door's backset matches the latch dimensions before drilling.
- Compatibility: Designed specifically for internal doors requiring a 64mm latch. Check your existing door handles to ensure they support bolt-through fixings.
- Maintenance: Occasionally check that the screws on your door furniture are tight. If the latch becomes stiff, a small amount of dry lubricant can be applied to the latch bolt to maintain smooth operation. Avoid using heavy oils that may attract dust and debris.
