2.1 Cremone Lock (Locking System)

The mission of 2Fold™ is to be the thinnest folding door system in the world. The patent pending combination of steel and wood created the ability to have sash members that are an incredible 1” in face dimension. Once this was accomplished, we developed the 2.1 Cremone Lock: a locking system compatible with both the mission and the framing system.

Folding doors of all designs use one of two locking strategies:

  1. Surface bolts mounting at the top and bottom of the locking jamb. In order to lock or unlock the door pair, you need to reach the upper bolt at the top of the door and then bend over to reach the lower bolt. Consequently, doors over 7 feet in height are almost impossible to unlock without a stool or ladder. Also, the surface mounted hardware is bulky to look at.
  2. A multi-point locking system like the Brio 286. If we were designing a typical folding door, this would be our choice. The lock is wonderfully built and works well. The only visible part is the handle and deadlock lever. The problem with this is that “typical” folding doors have wide sash stiles that can handle the installation of the locking system. To work with the very best traditional system would have meant making the sash frame 2.5 times larger. That was NOT acceptable to 2Fold.

More Security and Peace of Mind with the Magic of the 2.1 Cremone Lock

The 2.1 Cremone Lock is similar to the multi-point lock that can be bought for installation in almost any traditional folding door. It has 2 locking points, top and bottom, and also has just 1 operating lever. The magic with 2.1 is that no regularly manufactured lock would fit into the 3/8” lock rebate of 2Fold. We had to expand our pending patent to include a unique combination of stainless steel components that would securely lock the door, fit into the space, and operate with a single lever.

Once we accomplished this, we took it one step further. We allow the locking gear to over-rotate in the locking position. As a result, a thief attempting to break into your home using the “credit card” trick would be defeated. Because, the harder they try to push the bolt down, the more locked it becomes. Frustrating for them, Safety for you.
