The Simpson Strong-Tie JHA450-91 joist hanger offers adjustable height and extended legs for secure, adaptable installation, ensuring a stable connection.

This joist hanger, model JHA450-91, is specifically designed for use with solid sawn timber joists. It is not intended for engineered lumber, I-joists, or other manufactured wood products.
No, you must use the specific fasteners recommended by Simpson Strong-Tie for this joist hanger. Using incorrect fasteners will compromise the structural integrity and load-bearing capacity.
The adjustable height feature allows for slight vertical positioning adjustments during installation, helping to achieve a level surface or compensate for minor variations in the supporting structure.
The speed prong is a pre-installed feature that helps temporarily hold the joist hanger in the correct position against the header or beam, allowing for easier alignment and initial fastening before the final load-bearing screws or nails are driven.
The dimensions of this joist hanger are approximately 455mm in length (strap height) and 91mm in width. The actual seat width for the joist is typically 38mm (1.5 inches).
Yes, the pre-galvanised mild steel provides corrosion resistance, making it suitable for outdoor applications. However, always ensure appropriate fasteners are used and consider the specific environmental conditions.
It is strongly advised not to bend or modify the joist hanger, as this can compromise its structural integrity and void its load-bearing capacity ratings. Use the hanger as intended by the manufacturer.
Ensure the speed prong is fully engaged in the wood. If issues persist, a temporary clamp or assistance may be needed for initial positioning.
Check if the supporting member or joist is square. Minor adjustments may be possible with the adjustable height feature, but significant misalignment may require alternative solutions or joist trimming.
Verify that the correct type and quantity of fasteners have been used according to Simpson Strong-Tie specifications. Ensure all fasteners are fully driven and secure.
Minor surface rust on pre-galvanised steel is normal and does not typically affect structural integrity. If significant corrosion or flaking occurs, the hanger may need replacement. Clean gently with a damp cloth.
