Roof-mounted Attachment

The five ways to rigidly attach equipment to a roof are:

• Using leveling stanchions—also called post and beam.
• To seismic built-up or seismic pre-manufactured curb.
• To wood frame.
• Using a pre-manufactured seismic vibration isolation curb or leveling stanchions with equipment support frame.
• Using restrained springs on leveling stanchions.
