I have two pieces of Perspex to go either side of my balcony railings (for privacy). I have glued the inside piece to the railings but do not want to do this with the outside piece. Would like to be able to detach outside piece. How can I bolt it to the other piece? Width of railing and Perspex is 21mm. Also needs to blend in with Perspex which is white. Any ideas? Thank you
