NotchTrak® NT

NotchTrack NT

Wall Backing & Bridging Alternative

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.

  • Meets Osha and IBC load requirements
  • Meets OSHPD 2013 CBC Standard Backing Details for Cabinet and Grab Bar (Details ST5.00 and ST5.03)
  • All material made from 50 KSI Steel
  • Notches every 16" or 24" o.c. to accomodate most wall stud spacing
