In high-end architectural joinery, the 200mm lever flush bolt is the preferred choice for securing the secondary leaf of French doors, double entryways, and oversized room dividers. While smaller bolts are suitable for lightweight cupboards, the 200mm lever flush bolt provides the extended body and internal leverage required to manage the weight and movement of full-sized timber doors. Designed to be morticed into the edge or the face of the door, this hardware remains entirely unobtrusive when the doors are closed, preserving the clean, uninterrupted lines of your interior design.

The defining feature of the 200mm lever flush bolt is its ergonomic “flip lever.” Unlike slide-button variants that can be difficult to operate, the lever mechanism provides a mechanical advantage, allowing the user to throw the heavy steel bolt deep into the frame or floor with minimal effort. This ensures that the “slave leaf” remains a rigid, immovable anchor for the primary door’s lock.

Why the 200mm Profile is the Industry Standard

The 200mm (8-inch) length is specifically engineered to provide a deep backset and a long bolt throw. This extra length allows the 200mm lever flush bolt to bridge larger gaps between the door and the frame, which is essential for older properties or heavy doors that may have slight natural movement.

High-Torque Flip Lever: The 200mm lever flush bolt utilizes a pivoting arm that makes engaging the bolt effortless, even for users with limited hand strength.
Deep 20mm Bolt Throw: Ensures a secure, deep engagement into the head of the frame or the floor socket for maximum security.
Flush-to-Timber Finish: Once morticed, the 200mm lever flush bolt sits perfectly level with the door surface, preventing snags on clothing or weatherstripping.
Solid Forged Construction: Crafted from high-density architectural brass to resist bending and shearing under significant pressure.
Internal Tension Springs: Every 200mm lever flush bolt is fitted with a heavy-duty spring to prevent the bolt from “dropping” or rattling over time.
Architectural Finish Palette: Available in a range of luxury tones, including Satin Chrome, Polished Nickel, Matte Black, and Antique Brass.
Reinforced Perimeter Security: Acts as a heavy-duty deadbolt, providing two-point locking (top and bottom) for total peace of mind.

Achieve a Master-Class Finish

Installing a 200mm lever flush bolt is the hallmark of a professional door installation. For a truly high-end result, we recommend “pairing” these bolts at both the top and bottom of the door. This prevents the door from bowing at the corners and ensures a perfect, airtight seal against the frame’s weatherstripping.

Maintenance is negligible; the 200mm lever flush bolt is protected from the elements by the door itself. A light application of silicone lubricant to the pivot point once every few years will keep the action feeling “factory new” for decades. Elevate your entryway with a 200mm lever flush bolt that offers the perfect balance of invisible design and formidable strength.

This 20 x 200mm lever action flush bolt with radius forends is designed for strength, reliability, and ease of use. It is ideal for securing the inactive leaf of double doors or any door that requires extra fastening. The lever handle makes operation smooth and effortless, allowing the bolt to slide securely into position with a simple movement. The radius forends provide a neat and professional finish, ensuring the flush bolt fits neatly into the door edge while maintaining a clean appearance.
