TradeReady® Floor Joist Blocking
Quote requiredPre-cut to fit 12", 16", or 24" joist spacing
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. 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.
