Survey details
How to use it: Work top to bottom while you're at the unit. Answer the curb-adapter question in Section 4 first — if an adapter is already installed, the tool opens extra fields for the original curb's hidden duct openings, which you'll need to spec the next swap. Hit Print / Save PDF when you're done for a clean copy to drop in the job file. Pair it with the Cross-Reference tool to pull the matching submittal.
