Features

Material

Pre-galvanised mild steel.

Features

A galvanised joist hanger that provides great support with ease of installation.
Published performance values are based upon 3.75 x 30mm square twist nails being used throughout.
Wider strap provides more surface area on the supporting timber and allows increased nail spacing, enhancing the performance of the critical hanger-to-support part of the connection.
Minimum and maximum nailing schedules are stamped into the strap providing correct installation information for site operatives.
Speed-prong holds the hanger in position to allow easier attachment. The installer no longer has to try to hold hanger, joist and nail with one hand and swing a hammer with the other!
JHA270 range features a location tab which allows easier alignment of the hanger.
The model number and size is stamped into the seat of the hanger for easy identification, even after installation.

Application

Suitable On

Solid sawn timber joists

Installation

Alternative installation methods are available depending on the availability of nailing surface.

Maximum Nailing: All nails must be applied according to the table.

Minimum Nailing: For a lower installed cost the minimum nailing schedule can be used. A minimum wrap over of 45mm is required.

Loft Conversions (JHA450 Range): For applications where the hanger extends below the support. Install top, face, and joist nails according to the table. A minimum wrap over of 45mm is required or maximum nailing.
