Do Not Risk Non-Certified Frame Seals. Ceco frame seals are UL certified and approved for rated openings. When compliance matters, use hardware that is tested and documented.
On fire-rated commercial door openings, perimeter gasketing is not optional - it is a critical component of the opening’s life-safety and code compliance. Installing a non-certified perimeter seal can jeopardize inspections, delay occupancy, or leave an opening out of compliance.
The Ceco UL Certified Screw-On Perimeter Bulb Seal is engineered for spec-driven commercial projects where certification, documentation, and proven performance matter. Designed for commercial door frames, it delivers a tight, durable perimeter seal while supporting strict fire and positive pressure requirements.
Don’t get caught installing a perimeter seal that isn’t certified. When inspectors are involved and documentation is required, Ceco delivers confidence and compliance.
This product is CERTIFIED by UL to both fire-test and positive pressure standards for application to rated openings:
This seal is also Air Infiltration Tested to ASTM E283 (Standard Test Method for Determining Rate of Air Leakage Through Exterior Windows, Curtain Walls, and Doors), supporting draft control and energy-efficiency expectations in commercial buildings.
Ceco products are selected for compliance and longevity - not for being the lowest-cost option. This perimeter seal supports ANSI (American National Standards Institute) certification and IBC compliance, making it suitable for healthcare, education, industrial, and commercial projects.
