Simpson Strong-Tie JHA450/50 Long Leg Adjustable Joist Hanger 50mm

Summary

The Simpson Strong-Tie JHA450/50 is a long-leg, height-adjustable joist hanger engineered to support 50mm wide solid sawn timber joists from carrying timber members. Manufactured from pre-galvanised mild steel and carrying European Technical Approval, it is the heavy-duty choice for loft conversions, deep floor zones, and any application where the hanger extends below the support. Its extended 475mm leg profile and thicker gauge steel deliver superior structural load capacities over the standard JHA270 range.

Features

• Height-adjustable strap design for versatile installation - can be fixed to the face of the carrying member or wrapped over the top for higher performance
• Long-leg (JHA450) configuration with a total height of 475mm, suited to loft conversions and deeper floor zones
• Manufactured from pre-galvanised mild steel for corrosion resistance and durability
• Wider strap provides greater surface area on the supporting timber, improving nail spacing and enhancing hanger-to-support connection performance
• Speed-prong holds the hanger in position during installation, allowing one-handed fixing
• Minimum and maximum nailing schedules stamped into the strap for on-site guidance
• Model number and size stamped into the seat of the hanger for easy identification
• European Technical Approval (ETA) for use in structural construction
• Published performance values based on 3.75 x 30mm square twist nails throughout
