Metal Wall Mirrors I Am Looking For A Metal Scissor Arm Extension That Are Used Between Mirrors And Wall Mounts??

I am looking for a metal scissor arm extension that are used between mirrors and wall mounts?? - metal wall mirrors

I try to buy, just want to know the song, and buy, where it was only this part. The fact that the manufacturers themselves? If someone can point out that web site will always be grateful!

Thank you!
