I guess my shrink wrap was catching too much wind this winter. Two stanchions have lifted off of the rail. Two screw heads were broken and the other two are 1/4" inch or more pulled out. I used a scope to see what's under the rail below and there are no backing plates or nuts. The screws are machine screws not a lag type screw. Does anyone know how I should go about fixing this? I don't want to tear it off until I have a plan. Maybe the nuts or a plate with nuts are embedded into the fiberglass? I can't be the only one to ever have had this problem. Thank you in advance!
