For wood structural members having a moisture content of less than 16 per cent at time of installation and used under dry
conditions, the deflection resulting from L + 0.5D is permitted to be substituted for the deflection resulting from L + D.
Note that MASON-LITE cannot accept responsibility for structural floor support details. All drawings are presented as mere
illustrations to indicate the presence of the underlying floor system. It is the responsibility of the general contractor/installer to
consult with a local licensed design professional for guidance in building a proper floor support system.
