Equipment Mounting Angles are supplied in pairs to provide 19” mounting positions. Square slots designed to accept captive cage Nuts are located on universal centers. These Mounting Angles can be attached directly to the corner posts of the cabinets, or to the horizontal supports provided. With this arrangement front-to-rear adjustment is possible throughout the depth of the cabinets, so as to provide recessing from front and rear doors. These 19″ mounting angles are included in the scope of supply and need not be ordered separately.
