Home Improvement Asked by Kent Poppenhouse on November 27, 2020
My back patio roof is a flat roof with 2×6 rafters which look to be connected to the house using joist hangers. The far end of the rafters sit on a 4×12 beam.
With the weight of the swing and people, call it 500-600 lbs, is it ok to hang from 2 rafters?
Or is there concern the joist hangers would fail?
2 x 6 joist hangers are rated for a minimum of 400 lbs load at a 45 deg. angle, slightly more at a shallower angle. So two joists should be good for 800 lbs total.
Or if you are concerned, attach a 1" steel pipe across multiple rafters, then attach the swing to the pipe.
