Intermediate 11-7/8” Parallam Plus members shall be spaced at 6 equal bays anchored to the ledger with stainless steel joist hangers will serve as the support structure of the netting. ALL framing members must be cut longer than span need to create a compression fit between marble architrave beams. The netting will consists of a heavy duty, double stranded, nylon mesh, 2-1/2 inch square mesh maximum, paired with a 3/8 inch knitted polyethylene mesh liner. This netting will be attached to the top of the 11-7/8” Parallam Plus frame system with steel snap clips on a 3/8 inch diameter stainless steel perimeter cable looped through stainless steel eye bolts that are lagged into the tops of the 11-7/8” Parallam Plus wood framing members.

11-7/8” Parallam Plus perimeter wood ledgers to cover the dimensions of 19’-5” wide x 18’-9” deep.

11-7/8” Parallam Plus structural framing to span a distance of 18’-9”.

Design load requirements for the netting system shall be capable of arresting 250 pounds at a distance of 5 feet.

Cables, boarder edging and snap clips must have a minimum breaking strength of 5,000 pounds.

1. Contractor will provide a structural engineer licensed in the District of Columbia, Maryland or Virginia to perform and be responsible for the design of netting and structural support systems.
