Frameless mirror installation hardware is sold separately. When using four (4) invisible mirror clips to hang your mirror; two (2) at the top, two (2) at the bottom, you don't risk sideways mirror movement. https://www.glassupply.com/shop/invisible-mirror-clip/
For bigger mirrors and extra safety, glue your mirror to your wall with adhesive and double-sided tape in addition to mirror clip installation. https://www.glassupply.com/shop/mirror-adhesive-double-face-tape-installation-kit/
