The J Bar channel is a mirror mounting hardware accessory used to hang frameless wall mounted mirrors by supporting the bottom portion of the mirror. These bottom supports will provide a sturdy and seamless mirror installation. J Bars can fit up to 1/4" of an inch thick mirrors and are ideal for flat polished mirrors, where the mirror's edges will rest inside of the J-bar. Be sure to check that your walls are relatively flat and plumb before installing the J-bar.
For bevel polished and decorative edged mirrors, we recommend the L Bar Support.
