lågehållare

Lågehållare, often translated as "door holder" or "door retainer," is a device used to keep a door open or in a specific position. These mechanisms prevent doors from swinging shut due to gravity, drafts, or other forces. They are common in various settings, including residential buildings, vehicles, and industrial applications.

There are several types of lågehållare. Some are simple mechanical devices that physically latch onto the door or frame, such as a hook and eye system or a wedge. Others are more complex, employing magnetic forces to hold the door. Magnetic door holders typically consist of a magnet attached to the wall or floor and a metal plate on the door; when the door is close enough, the magnet attracts the plate, securing the door. Pneumatic and hydraulic door holders are also used, particularly in heavy-duty applications, providing controlled opening and closing with damping.

The primary purpose of a lågehållare is convenience and safety. In homes, they can prevent doors from banging against walls or allow for easy passage through doorways. In commercial spaces, they are often used to keep fire doors open for accessibility, though regulations typically require these to have automatic closing mechanisms. In vehicles, such as on boats or RVs, lågehållare are essential for keeping cabinet doors or entry doors open in potentially unstable conditions. The design and strength of a lågehållare are chosen based on the weight and intended use of the door it is securing.
