Can a 20' 6×12 rdwood be safely supported by 2 redwood corbels at each end 17'apart?
This is for an arbor over a 16′ garage door. The house is stucco’d and there’s 5 1/2" of foam trim around the door, so the closest I can get the corbels mounted is at 17′. They’re 6×10 or 6×12 corbels. They’re bulged at the bottom and end to end they’re 31.5" with about 7" of landing at the wall end as well as at the top. If this is possible, can these simply be lagged-in thru the stucco and into the wall? I think there’s 6x’s in therenext to the kings. There will be a 2×12(20′)ledger lagged into the gar. header and 4x4s laying across the top at 16-20 in. on center. Any help guys, please and thanks.. Is 7" 3/8 lag-screws enough? Maybe little clips on the side? It just doesnt seem like this will work.
