For temporary installation of a screen to the wall, the screen must be fitted with a bracket with three-point coupling and a wall-truss module. The wall-truss module can be mounted to the wall and has three "keyholes" in which the bracket (fitted with coupling bushes) is hung. Both horizontally and vertically a hole pattern for 30 cm truss is integrated, with 2 trigger clamps the module can be fixed to the truss. Lockable with a padlock (optional).
