The door holders allow fire doors to be held open. The use of door holders is recommended in public places with a high risk of fire or vandalism such as schools, communities, public services, etc. Specially designed for ceiling or wall mounting, they can be oriented horizontally or vertically with the use of some complementary accessories. In general, they are delivered with a fixed armature contact-plate (réf. APPO0001). These door holders can be electromagnetic or just magnetic according to your preferences and uses.
