Specially designed fixing clamps are used to attach wall fasteners and safety cage hoops to ladder uprights. These fixing clamps can be clipped to the ladder uprights at any desired position. A large range of wall fasteners are available for fast and easy installation on most support structures. The ladder can be fitted parallel or perpendicular to the wall. The vertical distance between wall fasteners should not exceed 9' 0", except when reinforced uprights are used.

Fixing clamps can be used in two ways. They can be fixed to allow for vertical movement. The fitting allowing vertical movement is used for long ladders, to  accommodate thermal expansion of ladders and the building structures.
