TradeReady® Floor Joist Blocking

Quick and efficient system that prevents joist rotation and accommodates mechanical passing

TradeReady Floor Joist Blocking is one of the primary components that make up the TradeReady floor bracing system.

TradeReady Blocking features a large extruded hole to accommodate HVAC, mechanical, plumbing and sprinkler runs.

TradeReady Blocking is pre-cut and formed to fit securely between the floor joists to prevent joist rotation. Pre-punched holes in the connection legs are added for quick attachment to each floor joist. Structural blocking is an economical alternative to TradeReady Structural Bridging (TDSB) or Flat Strapping.

  • Pre-cut to fit 12", 16", or 24" joist spacing
  • Pre-punched holes for quick attachment to floor joists
  • Available in 7-1/4”, 8”, 9-1/4”, 10”, 11-1/4”, 12" and 14” deep members
  • Extruded hole sizes range based on member depth:
    • 4-1/2” x 7” hole for 7-1/4” and 8” blocking systems
    • 6-1/2” x 9” hole for 9-1/4”, 10”, 11-1/4”,12" and 14” blocking systems
       

Floor Joist Blocking is typically used in conjunction with a continuous row of TradeReady Structural Bridging (TDSB) that ties the floor system to the structure allowing bracing against lateral movement.
