Project Tubular Latch 76mm Square Forend Heavy Duty Internal Door Latch Durable Hardware for Smooth Operation

The Project Tubular Latch is designed to be the “workhorse” of modern interior ironmongery. Unlike specialized security locks, the tubular latch is a non-locking mechanism used purely to keep internal doors closed. Its “tubular” design refers to the cylindrical body, which allows for rapid installation using a standard 25mm spade bit or auger—significantly reducing labor time on large-scale construction projects.

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

Why the Project Tubular Latch is the Professional Choice

• Standardized 64mm/76mm Depths: Available in the most common industry sizes, ensuring compatibility with standard door stiles and existing handle backsets.

• 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 latches.

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

• Grade 304 Stainless Steel Faceplates: Naturally resistant to corrosion and wear, ensuring the visible parts of the hardware remain pristine even in humid areas like en-suites and kitchens.

• Universal Handing: The bolt can be easily reversed without opening the case, making it suitable for both left and right-handed doors.

• Contractor-Friendly Installation: The simple cylindrical bore-hole requirement makes this the fastest latch to install, saving significant time on multi-door projects.

Professional Installation for Maximum Longevity

To ensure the 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 angled, the spindle will bind, making the handle difficult to turn.

2. Recess for Flush Fit: 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 close smoothly.

3. Spindle Alignment: Ensure your handle spindle passes through the center of the latch follower. If the handle is fixed slightly off-center, it will put uneven pressure on the latch spring, leading to premature wear.

4. Dust Box Installation: Always use the provided strike plate and, if available, a plastic dust box behind it. This prevents wood shavings from entering the mechanism and provides a cleaner finish inside the door jamb.

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.
