Lol when did lifting 1-200lb wet rugs become such a safety concern? l
When 5 of 'em equal 1000 pounds ???
That 2x6 is carrying more load than it should for that great of a span . (assuming max possible weight)
a center post on each side would fix that.
or double the load bearing 2x6s (one on each side of post) and
bolted like a deck beam...
and if you did that, it would allow you to use hanging hardware to easily move the racks fore or aft instead of being fixed stationary (
maybe)..not sure how wench system works)
if you're screwed to the back wall, that would be good to keep the front to rear sway.
left to right sway out front is questionable though.
couple 45 degree cross supports would help greatly
implement the above reinforcement suggestions and I'll issue an official redneck certified "oakie doakie" seal of approval
I'm just goofing off this weekend ..would love to come over to help you make it rock solid...wouldn't cost much at all in additional materials..and would be "lifetime" solid when we're done
..L.T.A.
