Pemko 325XGSS10BEN Extreme Gap Door Bottom Sweep — Satin Bronze, Neoprene Insert
The Pemko 325XGSS10BEN is a heavy-duty extreme gap door bottom sweep engineered specifically for commercial fire-rated door openings where door-to-floor or door-to-threshold clearances exceed the limits set by NFPA 80. Finished in Satin Bronze (10BE) and fitted with a durable neoprene seal insert, this surface-mounted, screw-applied U-channel sweep delivers a code-compliant, field-replaceable sealing solution for oversized door bottom gaps. Also referenced in the trade as an excessive-gap door bottom seal or commercial fire door bottom sweep, the 325XGSS10BEN is independently fire-tested by Intertek (Warnock Hersey) under listing IS47, qualifying it for use on rated door assemblies up to 1-1/2 hours of fire resistance.
Institutional Grade Features & Benefits
- Excessive-Gap Fire Door Solution: Purpose-built for door and frame clearances that exceed standard NFPA 80 tolerances, making it the correct specification choice when field conditions present oversized bottom gaps on fire-rated assemblies.
- Independently Fire-Tested: Listed by Intertek / Warnock Hersey (IS47) for use on fire-rated door assemblies up to 1-1/2 hours — providing verifiable third-party validation for AHJ review and code compliance documentation.
- Surface / Screw-Mounted U-Channel Design: Installs directly to the face or bottom edge of the door without routing or mortising, simplifying retrofit applications on existing commercial fire doors and reducing installation labor.
- Replaceable Neoprene Insert: The neoprene seal element is field-replaceable, extending the service life of the door hardware assembly and lowering long-term maintenance costs — a key specification advantage for high-traffic commercial openings.
- Satin Bronze (10BE) Finish: The 10BE satin bronze finish provides an architecturally coordinated appearance compatible with commercial door hardware suites specified in warm bronze tones, supporting finish consistency across the opening.
- NFPA 80 Compliance Support: Designed to restore code-compliant gap performance on fire-rated door openings, directly addressing the door clearance requirements of NFPA 80, Standard for Fire Doors and Other Opening Protectives.
- Commercial-Grade Construction: Pemko's stainless steel U-channel extrusion delivers the corrosion resistance and structural durability expected in institutional, healthcare, education, and commercial building environments.
