These are ideal for the clients who have bathroom wall mirrors already attached to their bathroom wall. They may be glued, may have a z-track, may have the plastic or metal clips etc. We offer replacements for the plastic clips if that is what is currently holding up their wall mirror. If their metal clips are snug against the mirror then those will work perfect without having to change anything out. If they have the metal clips that have a gap in between the mirror and the metal clip then let us know in advance along with the measurements on where these are currently placed on their wall mirror. We will customize your frame so that the frame will go over these metal clips and you will have no gap in between. Any customized order you may need help with please contact us and we will do our best to accommodate you and your project. Before & After Step 1. Measure the wall mirror.
