Inquiry (采购产品): hollow metal doors Good Evening. I have a company in VA. that will be hanging posters inside hollow metal bathroom doors. We will be hanging plexiglass frames to hold the posters.(16x 20 and 18 x 24) We wanted to ask what would be the best fastner to use? Would you advise the best method? Thank you for your time and thoughts.
