The Simpson Strongtie JHA450/47 Joist Hanger Jiffy is a galvanized steel Jiffy. It's used by trade professionals for supporting timber joists from timber members. The Joist Hanger has a wide strap and increased nail spacing for an easier installation. It has speed prongs which give a temporary attachment onto the timber so it frees up both hands for hammer and nails. Supplied as a single unit.
| The speed-prong means no more holding hammer, joist and nail in together and gives overall better performance. |
| Its Galvanised finish gives it a reliable and long term protection. |
| The wide strap increases the surface area and helps give a stronger connection. |
| JHA270 range features a location tab which allows easier alignment of the hanger. |
