A spec section rarely names one manufacturer. These carry documents in the library for the same section.

Past looking things up

Finding the document is the easy half.

Pulling one cut sheet takes a minute. Pulling every document a spec book demands, matched to the right rows and assembled behind transmittals, is the week that eats project engineers.

About these documents

Whose documents these are.

These documents belong to the manufacturers that publish them, and nothing here replaces their own published literature. SubPro indexes them so a contractor can find the current version for a submittal. To have one corrected, updated, or removed, write to pilots@sub-pro-ai.com. Full details on the document rights page.
