Release Buffer

When opened many sliding doors disappear in so-called wall pockets. This is the optimum solution – if there wasn’t the problem of the door handle for closing the door no longer being accessible. But in case the door is not opened completely, precious width of the passage is lost. In the worst case, especially in barrier-free buildings, this could require a wider, more expensive door.

The DICTATOR release buffer is a simple and reliable solution to this problem.

Usually the release buffer is mounted (invisibly) in the opening edge of the door. When opening the door the magnet buffer on the piston rod hits a counter plate. This at the same time keeps the door in the open position. If you want to close the door, you just have to press lightly against its edge and the integrated spring will push the door out of the wall pocket so far that the handle is accessible again.

The release buffer is available with two different spring forces. Usually the model with 85 N will be sufficient. The stronger version should only be choosen if the door is not smooth-running, e.g. when a brush seal is mounted.

Function scheme release bufferThe release buffer is usually mounted in the opening edge of the door leaf. This requires a corresponding boring in the door leaf.

Unless it is a door/frame of steel, the included counter plate has to be mounted as a counter part. It is needed for the magnet at the end of the piston rod that keeps the door safely in the open position.

In the wall pocket behind the opened door you only need a space of 25 mm for the release buffer.
