In Situ

— Suitable for use with Open Web Joists, I–Joists and trusses — Floor can be propped with acroprops and fully decked but must not be fully loaded until the masonry above has fully cured

— Where minimum of 3 courses (675mm) of masonry is required for hanger to achieve loads stated — The masonry above must be fully cured for 28 days prior to loading the floor — All hangers in this range do not provide restraint, therefore restraint straps may be required for joist applications (see pages 128 – 129)
