Lever action flush bolt – 20 x 200mm

In high-quality door specification, the 200mm Lever Action Flush Bolt is favored for its increased “grip” within the timber. While a standard 150mm bolt is sufficient for lightweight doors, the 200mm (8-inch) length provides extra structural reinforcement for heavy solid-core or fire-rated doors. The lever-action mechanism uses a flip-out handle to drive a hardened vertical bolt into the head or floor, ensuring that double doors remain perfectly flush and rattle-free.

Forged from Grade 304 Stainless Steel (SS304), this 200mm Lever Action Flush Bolt features a slim 20mm profile that sits entirely level with the door edge. This “concealed-fix” design is essential for modern aesthetics, providing a clean, snag-free surface that doesn’t interfere with the operation of the primary door leaf.

Why the 200mm Lever Action Bolt is the Professional Choice

• Enhanced Mechanical Leverage: The 200mm body allows for a slightly larger internal linkage, providing a smoother “flip” action and a more powerful bolt throw compared to smaller residential bolts.

• Deep Mortice Security: The 8-inch length distributes the stress of wind pressure or physical force across a larger section of the door timber, reducing the risk of the bolt “splitting out” under duress.

• Grade 304 Stainless Steel Build: Premium SS304 construction ensures the faceplate and internal rod are resistant to rust and pitting, making it suitable for both internal suites and external balcony doors.

   

• Positive Snap-Lock Action: The internal gear system is designed with a firm “click” at both the retracted and extended positions, preventing the bolt from vibrating loose or dropping over time.

• Universal 20mm Width: Fits standard router preparations for architectural flush bolts, making it a straightforward specification for joiners and door manufacturers.

• Durable Satin Finish: The Satin Stainless Steel (SSS) finish is highly resistant to scratches and matches other contemporary door hardware like handles and closers.

Professional Installation for 200mm Lever Action Flush Bolt

To ensure the 200mm Lever Action Flush Bolt operates with professional precision, follow these essential fitting steps:

1. Centered Mortice: Use a 20mm router bit and a template to ensure the recess is perfectly centered on the door edge. If the bolt is off-center, the lever may hit the rebate of the opposite door leaf.

2. Strike Plate Depth: Mark the frame or floor only after the bolt is installed in the door. Ensure the strike plate is recessed enough so that the bolt “clicks” into its fully extended position without hitting the bottom of the hole.

3. Top and Bottom Pairing: For the most secure installation on external doors, pair a 200mm Lever Action Flush Bolt at the top with a matching unit at the bottom. This prevents “warping” at the corners of tall timber doors.

4. Screw Selection: Use the provided stainless steel screws. For floor-mounted strikes into masonry, ensure you use high-quality wall plugs to prevent the strike plate from becoming loose over time.

5. Initial Maintenance: Apply a small drop of dry PTFE lubricant to the pivot pin of the lever before installation. This ensures a “silk-smooth” operation and prevents the metal-on-metal squeak often found in cheaper alternatives.
