Me???

A couple of months ago I was reorganizing the shop, and I put my flaps on a rack off one of the rafters. I meant to put a stop of some sort to catch the edge so it couldn't slide off. Well, I got distracted by family matters and about an hour later heard a crash. Go downstairs to find one flap on the floor. Huge dent in the corner, completely unfixable. Ordered all new flap parts , about $130.00. Learned my lesson too.......all parts secured from here on out
