Supports are the vertical members designed to hold the deck and completed loft. Cross supports are used for stability and reduction of wobble. Cross beams are horizontal members attached to the cross supports, designed to hold the deck and deck joists. They must be bolted to the supports. Screws are recommended for attaching these joists.
Cleats are beams running parallel with the cross beams and are used to support desk joists.
Hangers may be used instead of cleats to support joists. These are metal brackets that should be nailed into the cross beams. Wedges are used as padding between the supports and wall for stability and reduction of wobble. Wood should be treated to meet fire retardant standards. These specifications are to be considered minimum and are to be strictly met.
