How to attach something to a Permacast column
I'm interested in attaching some wrought iron hooks onto my Permacast columns on my covered porch to hang hanging flower baskets. I drilled a pilot hole, not knowing if it was hollow or solid core and DOH! It's hollow. My question is, what can I use to anchor the screw in the column to hold the weight of a hanging basket? I'm kind of already committed to doing something since I've already drilled a hole. Please help with your suggestions!!
