The 230-B3L is used for supporting mini-split condensing units.  The brackets feature a cross bar that is attached to a wall, and two L-shaped brackets that are hooked and bolted into the cross bar.  The condensing unit is mounted onto the L-shaped brackets and fastened using the bolts and anti-vibration washers provided. 

The type 3 bracket features a locking mechanism called Easy-Fit™.  Easy-Fit™ enables the arms to be joined to the uprights in a matter of seconds.  A spring-lock automatically secures the joint, preventing the arms from being dislodged accidentally.  This bracket is furnished complete with a bubble level to make correct installation of the crossbar easier.

This bracket's use may violate California building code.
