This ready-to-use collar features intumescent technology that expands when exposed to heat, sealing off penetrations to maintain fire ratings. The collar meets \u003ca href=\"\/resources\/building-codes-standards\/fire-inspection-compliance\/astm-e814\"\u003eASTM-E814\u003c\/a\u003e standards and carries UL classification for reliable fire protection performance.\u003c\/p\u003e\n\n\u003cp\u003eInstallation is straightforward with this pre-manufactured collar system, reducing labor costs compared to field-applied alternatives. The intumescent material activates at elevated temperatures, expanding to close off the penetration and prevent fire and smoke passage. Made in the USA, this collar incorporates EcoSeal technology for enhanced environmental performance while maintaining full compliance with fire safety codes. The UL classified design ensures consistent performance in fire-rated assemblies.\u003c\/p\u003e\n\n\u003cp\u003eThese collars work effectively in commercial and residential construction where plastic piping systems penetrate fire-rated walls or floors.
