    Which kind of Magnetic door holder will be better? Wall mounted or the Floor mounted?  S4A teaches you how to choose

    The Magnetic door holder is a hardware accessory used by every household. It can protect the door leaf and prevent the door leaf from being damaged due to strong collisions. The Magnetic door holder can be divided into wall-mounted and floor mounted from the installation method. Many families will be entangled when choosing: which one is better to choose? Today, S4A will help you analyze it.Understanding Magnetic door holderA magnetic door holder, commonly known as a door bumper, is a device that can hold the door leaf when the door leaf is opened. According to the installation form, the Magnetic door stop is divided into the wall-mounted type and floor-mounted type.A small metal plate is attached to the door and is positioned to come in direct contact with the electromagnet. When energized, the electromagnet will hold onto the metal plate to hold the door open. Mag hold-open devices are connected to the fire alarm system or life safety system.The Magnetic door holder is installed behind the door. When the door is opened, the door is stabilized by its magnetism to prevent it from closing automatically when the wind blows. This is especially suitable for the elderly and children at home, effectively preventing the elderly and children from accidentally locking themselves into the house. inside.The difference between wall-mounted and floor mountedThe function of wall mounted and floor mounted is to prevent the door of the house from touching the wall and damaging the wall, but both wall-mounted and ground-mounted have their own advantages and disadvantages.Wall-mounted1. Under normal circumstances, most households use wall-mounted, which is installed on the wall behind the door, which does not take up space and is more securely fixed.In addition, the wall-mounted does not occupy floor space, has a good decorative effect, does not affect the aesthetics of the home, and is more convenient to use.2. Wall mounted has high requirements on the wall surface. Some owners worry that nailing the door stopper to the wall may cause damage to the wall due to excessive tension. In fact, it is normal to have such a worry.If the wall of the house is made of cement and mixed with a lot of sand, this kind of wall is likely to damage the wall if it is sucked by the wall.Ground-mounted The ground-mounted is installed on the ground, it occupies a small floor area, and the sound insulation effect is better. The distance between the door and the wall is not high, and there is no requirement for the wall.2. When it comes to ground-mounted, it is estimated that some owners feel that ground-mounted is too intrusive, and they are easy to trip when they are not paying attention. When cleaning the room, the ground around the floor-mounted is not easy to clean, and it is easy to rust after a long time of use.The Emergency Door Holder is a powerful "weapon" to protect the wall and door leaf. Choosing a suitable door stopper can prolong the service life of the door...
