NOP Moisture Barrier Plates
Truss & Rafter
Moisture Barrier Plates protect the bottom chords of trusses from
moisture damage caused by direct contact with concrete. These plates
eliminate the need for more expensive treated wood plates.
Materials: See chart
Finish: G90 galvanizing
Codes: See page 11 for Code Reference Chart
Installation:
• Use all specied fasteners. See Product Notes, page 17.
• Pre-attach to truss bottom chord or rafter using pre-punched prongs
and/or 6d common nails to prevent wood-to-concrete contact.
