Spec-equivalent SB5 SKUs for door perimeter, threshold, and acoustic seal systems
Zero International (part of Allegion) is a commercial-grade door perimeter sealing supplier with a strong acoustic and fire-rated assembly lineup. Their catalog is application-first, tiered between Preferred and Everyday product lines. Distribution is via architectural hardware channels. SB5 sources to the same BHMA, UL, NFPA, and ASTM acoustic-rating standards the Zero catalog publishes against.
About this cross-reference
SB5 is not affiliated with Zero International. Zero International is a separate company; their trademarks belong to them. This page shows which SB5 components are built to the same published specification standards (BHMA A156.22 Grade 1; UL 10C / 1784, AAMA 702; ASTM E90 / E413 / E1408, BHMA A156.21; ADA/ANSI A117.1, BHMA A156.22 Grade 1; UL 10C; UL 1784; ASTM E283/E90) so OEM buyers searching for a Zero International-equivalent can find the matching SB5 SKU. Specs listed for Zero International products reflect the public industry standard — not Zero International's proprietary tooling, formulation, or branding.
