Heavy Duty Tubular Deadbolt 64mm Complete with SSS Forends Strong Secure Door Lock

In modern architectural security, the 64mm Heavy Duty Tubular Deadbolt is the definitive “problem-solver” for doors where space is at a premium. With a 2.5-inch (64mm) case depth, this deadbolt is specifically designed to fit into standard narrow-stile doors without compromising the structural integrity of the timber. Unlike a spring-loaded latch, this deadbolt features a squared, stationary bolt that provides a rigid mechanical link between the door and the frame, resisting “shimming” and forced entry attempts.

Constructed with Satin Stainless Steel (SSS) forends, this 64mm Heavy Duty Tubular Deadbolt is designed to match high-end lever handles and pull bars. The “Heavy Duty” internal mechanism is engineered for high-torque applications, ensuring that whether you are using a standard thumbturn or a high-security 8mm spindle, the bolt operation remains crisp, positive, and reliable.

Why the 64mm Heavy Duty Deadbolt is the Industry Standard

• Hardened Steel Security Bolt: The core bolt is forged from toughened steel, designed to resist hacksawing and physical impact, providing a formidable defense for both internal and external doors.

• Standard 44mm Backset: The 64mm Heavy Duty Tubular Deadbolt features a 44mm backset (the distance from the door edge to the center of the spindle), aligning perfectly with standard residential door handle placements.

• Grade 304 Stainless Steel Forends: Premium SS304 faceplates ensure the lock is resistant to corrosion and tarnishing, making it suitable for use in high-moisture areas like bathrooms or coastal properties.

   

• Reinforced Box Strike Plate: Each unit is supplied with a heavy-duty strike box that reinforces the door jamb, preventing the timber from splitting if the door is subjected to physical force.

• Universal 5mm/8mm Spindle Compatibility: Available in configurations to suit both domestic 5mm privacy turns and heavy-duty commercial 8mm spindles.

• Fire Rated Integrity: Fully tested and certified for use on 30-minute and 60-minute timber fire doors (FD30/FD60).

Technical Specifications of 64mm Heavy Duty Tubular Deadbolt

Professional Installation for a Secure Finish

The performance of a 64mm Heavy Duty Tubular Deadbolt relies on a precise, “snug” fit within the door’s mortice.

1. Precision Boring: Use a 22mm or 25mm spade bit (depending on the case diameter) to drill the horizontal hole. It is essential to drill straight; if the hole is angled, the spindle will not align with the thumbturn, causing the lock to jam.

2. Clean Faceplate Recessing: Use a sharp 25mm chisel to create a shallow recess for the faceplate. The plate should sit perfectly flush with the door edge to ensure the door closes smoothly without catching on the frame.

3. Strike Plate Alignment: Close the door and mark the exact center of the bolt on the door jamb. The strike plate must be perfectly centered. If it is even 2mm off, the deadbolt will “rub,” making it difficult to operate.

4. Security Screws: For the strike plate, use 35mm to 50mm stainless steel screws. Longer screws reach into the structural timber of the door frame, significantly increasing the force required to kick the door in.

5. Dry Lubrication: If the bolt feels stiff after installation, apply a small amount of dry graphite lubricant to the mechanism. Avoid using heavy oils or grease, as these attract dust and can gum up the heavy-duty internals over time.
