ABSTRACT:
A drywall furring system comprises a plurality of longitudinal carrying channels having congruent tongues co-planar with, spaced apart along and depending from the opposite flanges of the channels and a plurality of furring channels having pairs of slots spaced apart along the opposite flanges thereof. On opposite edges of the tongues there are tabs tapering upwardly from the rounded corners thereof and elongated, narrow fingers whose lower margins angle up from a point space apart from the distal edges of the tongues. The tabs and fingers have seats in the same horizontal plane and the fingers have retaining hooks extending up beyond the seats. A gridwork of the carrying channels and furring channels is constructed by aligning opposed congruent fingers of the former with a pair of slots in the latter and passing the fingers through the slots and pushing the opposite flanges of the furring channel over the rounded corners of the tongues so that the furring strips rest on the seats of the fingers and tabs. Gypsum wallboard is attached to the furring strips to form a ceiling. A linear metal ceiling or wall may be constructed by using furring strips having a decorative web to fashion the exterior surface.
