Manufacturers Covered

Built for the trade, by the trade.

Not another generic AI. Modulus DFH was built by a door hardware professional on the same catalogs, codes, and standards you use every day.

Product Specification

Ask for a hardware recommendation and get back specific model numbers, functions, finishes, and mounting configurations. Not generic advice — real part numbers.

Cross-Reference

Convert an Allegion hardware package to ASSA ABLOY, Hager, or dormakaba in seconds. Direct product-to-product equivalents.

Code Compliance

IBC, NFPA 80, NFPA 101, ADA, and state amendments built in. It knows Chicago's 8.5 lbf force limit.

Gotcha Detection

Flags fire-rating conflicts, panic hardware thresholds, fail-safe vs. fail-secure issues, and asks the right clarifying questions.

Industry Knowledge

DHI technical content, iDigHardware articles, SDI standards, BHMA bulletins, and DASMA technical data sheets.

Hardware Sets

Describe your opening — fire rating, occupancy, single or pair — and get a complete hardware group with every item specified from real catalogs.

What's inside the knowledge base.

Every answer is grounded in real manufacturer documentation and industry standards. No hallucinations — if it's not in the data, it tells you.
