24" x 36" FRFD Fire-Rated Floor Hatch – Acudor
Creating an opening on the floor that doesn't compromise the overall structure's fire rating is tricky. Many floor hatch models fail to meet industry standards. The 24" x 36" FRFD Fire-Rated Floor Hatch - Acudor provides a reliable and compliant access point that delays the spread of fire and smoke by up to 2 hours.
The FRFD seamlessly integrates into fire-rated floor assemblies. Its dual-frame design—with an aluminum top frame and stainless steel bottom frame—ensures durability and thermal isolation. The hatch's automatic closing mechanism, triggered by a UL-listed fusible link, guarantees reliable performance during critical moments.
Why Should You Use the FRFD?
- 2-Hour Fire Rating: The FRFD Fire-Rated Floor Hatch maintains the integrity of fire-rated floor assemblies, blocking fire and smoke from spreading for up to 2 hours.
- Automatic Closing Mechanism: The hatch features an automatic closing mechanism activated by a UL-listed 165-degree fusible link. This mechanism ensures that the hatch will close and latch automatically in case of a fire.
- Thermal Isolation: The dual-frame design includes a thermal break, which helps to prevent heat transfer between the hatch and the surrounding floor assembly.
- Superior Load Capacity: This floor hatch can safely support substantial weight without compromising performance, as it is reinforced to handle a live load of 150 lb./per sq. ft.
- Durable Construction: The FRFD, made with a 1/4" aluminum diamond plate door and stainless steel components, withstands heavy use and harsh environments.
