Spec-Equivalent Cross-Reference
Ultrafab Alternative
Spec-equivalent SB5 SKUs for the pile weatherstrip family
Ultrafab is a long-standing U.S. supplier of pile weatherstrip and related fenestration components. Their catalog is profile-type-first (pile, extruded, brush, die-cut), with stock status hidden behind a quote workflow. SB5 sources the same AAMA 701/702-23 pile geometries direct from vetted factories and inspects every run before release — same spec, no distributor markup chain.
About this cross-reference
SB5 is not affiliated with Ultrafab. Ultrafab is a separate company; their trademarks belong to them. This page shows which SB5 components are built to the same published specification standards (AAMA 701/702-23, AAMA 701/702-23 Class A, ABEC-1 / ABEC-3 bearing class; aluminum 6063-T5 housing) so OEM buyers searching for a Ultrafab-equivalent can find the matching SB5 SKU. Specs listed for Ultrafab products reflect the public industry standard — not Ultrafab's proprietary tooling, formulation, or branding.
