Project Tubular Latch 64mm Bolt Through Heavy Duty Internal Door Latch Smooth Reliable Operation Durable Hardware

The 64mm Project Tubular Latch is the preferred “short-backset” option for modern interior doors. The 64mm (2.5-inch) case length results in a 45mm backset (the distance from the door edge to the center of the handle spindle). This compact size is ideal for doors with narrower stiles or where a minimalist handle placement is desired, preventing the lever from appearing too deep into the door face.

Forged with Grade 304 Stainless Steel (SS304) forends, this 64mm Project Tubular Latch combines a clean, modern aesthetic with the mechanical resilience needed for thousands of daily operations. Whether specified for a new housing development or a commercial office refurb, the 64mm Project Latch offers the perfect balance of cost-efficiency and architectural quality.

Why the 64mm Project Tubular Latch is the Professional Choice

• Optimized 45mm Backset: Perfect for standard 35mm and 44mm thick internal doors, ensuring handles are positioned correctly even on narrow-style timber frames.

• Double-Spring Mechanism: Features a reinforced internal spring that provides a crisp “snap-back” for lever handles, preventing the “saggy handle” look common with inferior, lightweight latches.

• Guided Bolt Operation: The latch bolt is precision-molded to glide smoothly over the strike plate, reducing friction and noise for a quieter living or working environment.

• Grade 304 Stainless Steel Faceplates: Naturally resistant to corrosion and wear, ensuring the visible hardware remains pristine in kitchens, en-suites, and utility rooms.

• Universal Handing: The bolt features a curved face that works for both left and right-handed doors without the need for complex manual reversal.

• Rapid Installation: The 64mm tubular body allows for fast fitting using a standard 25mm spade bit, significantly reducing labor time on large-scale projects.

Professional Installation for Maximum Longevity

To ensure the 64mm Project Tubular Latch performs reliably for years, follow these essential installation steps:

1. Level Bore-Hole: Use a drill guide to ensure the 25mm hole for the latch body is perfectly level. If the latch is tilted, the spindle will bind against the follower, making the handle stiff to operate.

2. Flush Morticing: Chisel out the recess for the forend and the strike plate until they sit perfectly flush with the timber. A protruding latch plate can cause the door to “bounce” rather than latch securely.

3. Spindle Alignment: Ensure your handle spindle passes through the center of the latch follower. Even a 2mm misalignment can put uneven pressure on the latch spring, leading to premature mechanical failure.

4. Strike Plate Depth: Ensure the cavity behind the strike plate is deep enough for the bolt to fully extend. If the bolt hits the wood behind the plate, the handle may not return to the fully horizontal position.

5. Dry Lubrication: Apply a small amount of dry PTFE spray to the latch bolt every 12 months. This maintains the “silk-smooth” closing action and prevents the bolt from sticking during seasonal temperature changes.
