I just ran into a problem.
My ceiling sheetrocks are not attached directly to the joist, but to a layer of 1x3 furring strips which are then attached to the joists. See image below.
I cannot lower the attachment point of the housing flanges, so I think my only solution is to sister 2x4s to the joists on both sides of the housing, but lower them to flush with the strip. This would not only add a lot of work, but will also require me to shift the housing positions as some of them that are supposed to be located such that it's butt up against a joist, would have to be repositioned.
Any easier way?
Thanks,
MC
