The Truss Range provides options with shorter openings to fit between trusses. In the mid 1970’s roof structures changed from tradition joist and rafter roofs to modern engineered trusses, usually positioned at 900mm centres. The bottom chord of these trusses cannot be cut. In some applications, particularly hallways, standard attic ladders cannot be installed parallel with the trusses. The Truss Range solves this problem and is suitable for residential use for ceiling heights 2250mm to 3000mm.
