BSNN

Face Fix Hangers

BSNN ranges are heavy-duty hangers designed for applications requiring additional strength. Hangers are nailed using system CNA nails but have bolt holes for 12mm fasteners into the face. The hanger depth is to be at least 2/3 of the carried member heights to prevent rotation, unless additional lateral restraint is added to the top of the carried member.
