NotchTrak® NT provides solid wall stud bridging and/or backing systems to resist weak axis buckling and torsional rotation of members. NotchTrak NT also provides a solid backing solution to support handrails, wall-mounted shelving, and other equipment.
Material Composition
ASTM A1003/A1003M Structural Grade 50 (340) Type H, ST50H (ST340H): 50ksi (340MPa) minimum yield strength, 65ksi (450MPa) minimum tensile strength, with ASTM A653/A653M G60 (Z180) hot dipped galvanized coating, or equivalent.
Nomenclature
NotchTrak is manufactured in 12 ft. lengths. NotchTrak is designated by track depth in inches multiplied by 100, followed by type (NT), leg size, mil thickness and notch spacing.
