Want to build and hang a "bed/sofa" 64Lx32W on PT deck w/PT 7x2x10' rafters 16"oc. Spacing of rafters wrong for hanging. I can cut down size of the seating, but it defeats objective. QUESTION: can I place 4 "bridge supports" (for hanging bed @ corners) between the rafters using PT 2x4? 2x6? 2x8? along w/the appropriate hangers nailed into the rafters and ends of each 16" bridge (rafters are blocked)? Thanks for help
I would be installing 4"x4" joist hangers between the rafters and set in pieces of 4x4 P.T. lumber. If you are hanging the bed with chains, I'd drill through the 4x4's at the appropriate spot and insert bolts with washers and nuts on top. Good luck.
