The Diversitech ACB-30 is a wall bracket for mounting outside mini-split condensing units.  This is not needed for mounting the indoor air handlers.  Sold in sets of 2, each bracket has a triangular support for added strength.  At 600 lbs capacity for the pair, these brackets will work for the largest condensers, securely mounting to the wall for ease of maintenance and best performance.

Will accomodate 1/2" bolts for easy installation (not included). 

Some applications will require mounting holes be drilled into the horizontal arms to match the mounting points of the condensing unit and secure it into place (drill bit not included).
