Pemko 325XGSSWSPN Extreme Gap Door Bottom Sweep — White Suede (WSP) with Neoprene Insert
The Pemko 325XGSSWSPN is a commercial-grade door bottom sweep engineered specifically for excessive-gap door openings where standard door bottom seals fall short. Designed for use on fire-rated door assemblies up to 1-1/2 hours, this extreme gap sweep addresses door and frame clearances that exceed the thresholds defined by NFPA 80 — making it an essential compliance solution for fire door assemblies with larger-than-standard undercuts. The 325XGSSWSPN features a surface-mounted, screw-applied U-channel carrier finished in White Suede (WSP) with a field-replaceable neoprene seal insert, combining long-term serviceability with a clean, professional appearance. It is independently fire-tested through Intertek (Warnock Hersey listed) to Intertek IS47 as an excessive-gap solution — providing documented, third-party verification for AHJ (Authority Having Jurisdiction) submittals and fire door inspections.
Institutional Grade Features & Benefits
- Excessive-Gap Fire Door Solution: Purpose-built to address door-bottom clearances that exceed NFPA 80 maximums, restoring code compliance on rated door openings without costly door or frame modifications.
- Fire-Rated Door Compatibility: Independently fire-tested for use with rated door assemblies up to 1-1/2 hours, supporting compliance on the most common commercial and institutional fire door ratings.
- Intertek / Warnock Hersey Listed: Tested to Intertek IS47 — provides a recognized third-party listing for fire door inspection reports, building department submittals, and insurance documentation.
- Surface / Screw-Mount U-Channel: Straightforward installation on the face of the door bottom; no mortising or special tooling required, reducing installation labor on new construction and retrofit projects alike.
- Replaceable Neoprene Insert: The neoprene seal insert is field-replaceable, extending the service life of the U-channel carrier and reducing long-term maintenance costs in high-traffic commercial environments.
- White Suede (WSP) Finish: A neutral, low-glare finish that coordinates with painted hollow metal doors and frames common in healthcare, education, and institutional facilities.
- NFPA 80 Compliance Support: Specifically engineered to bring excessive-gap fire door openings into conformance with NFPA 80 requirements for door and frame clearances on fire-rated assemblies.
