Lever action flush bolt – 20 x 914mm

In modern commercial and luxury residential architecture, door heights frequently exceed the standard 2-meter mark. A 914mm Lever Action Flush Bolt (36 inches) is specifically designed for these oversized installations. By extending the internal rod mechanism, the operating lever is positioned at a convenient “waist-to-chest” height (typically around 1000mm to 1200mm from the floor), while the bolt itself engages securely into the head of the door frame nearly a meter above.

Forged from Grade 304 Stainless Steel (SS304), this 914mm Lever Action Flush Bolt offers the mechanical advantage required to throw a long internal rod smoothly. It provides a clean, flush-mounted aesthetic that is essential for rebated meeting stiles, ensuring that even the tallest double doors remain perfectly aligned and resistant to warping or forced entry.

Why the 914mm Lever Action Flush Bolt is the Professional Choice

• Ergonomic High-Door Access: The 36-inch length brings the control lever down to a comfortable height, ensuring compliance with accessibility standards and ease of use for all staff or residents.

• Anti-Warping Stability: On tall timber doors, a long flush bolt provides structural “bridging” that helps keep the meeting stiles straight, preventing the top of the door from bowing away from the frame over time.

• Grade 304 Stainless Steel Build: The faceplate and internal components are made from premium SS304, providing exceptional resistance to corrosion and the physical stresses of industrial or external use.

   

• Smooth Lever-Action Gear: The internal linkage is precision-engineered to provide a “click-lock” feel, ensuring the heavy vertical rod stays retracted or thrown without sliding under its own weight.

• Architectural Flush Fit: With a slim 20mm to 25mm width, the bolt sits completely level with the door edge, allowing for a seamless close between the active and inactive leaves of a double door set.

   

• Hygienic Satin Finish: The Satin Stainless Steel (SSS) finish is durable, easy to sanitize, and matches modern commercial door hardware, including pull handles and overhead closers.

Professional Installation for 914mm Flush Bolts

Installing a 914mm Lever Action Flush Bolt requires specialized preparation due to the length of the internal channel.

1. Deep-Channel Routing: Because the bolt body is nearly a meter long, a dedicated router jig is highly recommended. The channel must be perfectly straight; any curve in the mortice will cause the internal 914mm rod to “bind” against the timber, making the lever difficult to flip.

2. Top-Down Installation: This 914mm Lever Action Flush Bolt is almost exclusively used for the top of the door. Ensure the lever is positioned at a height that is reachable for the shortest likely user (usually centered around 1100mm from the floor).

3. Strike Plate Reinforcement: Given the leverage of a tall door, the strike plate in the head of the frame should be secured with 40mm or 50mm screws to ensure it can withstand wind pressure or attempted forced entry.

4. Gravity Resistance: Ensure the internal spring or “detent” within the lever mechanism is functioning correctly. A 914mm rod has significant weight; a high-quality bolt is required to prevent “gravity drop,” where the bolt vibrates down and scratches the floor or frame.

5. Dry Lubrication Maintenance: Due to the length of the rod, apply a light coat of dry PTFE spray along the rod before sliding it into the mortice. This reduces friction against the timber over the 914mm span.
