Simpson Strong-Tie Joist Hanger JHA450/137 Adjustable Height Strap 137mm Width - Triple Joist Support

Heavy-Duty Joist Hanger with Adjustable Height and Extra-Wide Strap

The Simpson Strong-Tie JHA450/137 is a high-performance, height-adjustable joist hanger engineered for supporting timber joists from other timber members in structural applications. Designed specifically to accommodate triple joist configurations (3 x 45mm), it offers exceptional stability, ease of installation, and reinforced support for demanding construction environments.

Key Features

• Adjustable Strap Height
  Allows precise alignment of joists at varying heights, ideal for non-uniform construction conditions or retrofit applications.

• Wider Strap for Enhanced Support
  Provides greater surface contact on the supporting timber and increases permissible nail spacing, improving load distribution and connection reliability.

• Speed-Prong Installation Aid
  Integrated prongs temporarily hold the hanger in place, freeing up hands during positioning and fastening.

• Dual Mounting Options
  Can be installed as face-fix or wrap-over, offering flexibility for different framing layouts.

• Clear Nailing Schedule Markings
  Minimum and maximum nailing instructions are stamped directly onto the strap, ensuring correct installation on site.

• Heavy-Duty Construction
  Made from 1.5mm thick pre-galvanised mild steel with extra-long legs for added strength and suitability for deeper joists.

• ETA (European Technical Approval)
  Certified for use in structural timber construction across Europe.
