Zero International 39A-36 – Frequently Asked Questions

1) Can the Zero International 39 door sweep go on a fire rated door?
The Zero International 39 sweep is fire rated per UL10c, so it belongs on a fire door assembly, and it carries ANSI/BHMA R3B434 certification as a door bottom seal. UL 10C is the positive pressure fire test standard for door assemblies, so when a submittal on a positive pressure opening asks for the gasketing to be listed, this is the listing it is asking about.
2) Does the Zero International 39 door sweep come in dark bronze to match the rest of our door hardware?
Dark Bronze is one of three finishes on the 39 sweep. The other two are Aluminum Clear Coated and Black. That is the complete finish range, so a building standardized on dark bronze hardware can carry the same finish down to the door bottoms, and the clear coated aluminum lines up with mill or clear aluminum storefront.
3) Should I use a door sweep like the Zero 39 or an automatic door bottom?
What is under the door decides it. A surface sweep like the 39 seals the bottom of the leaf all the time, which is what you want over a threshold or a hard floor with a consistent gap under the door. An automatic door bottom lifts as the door swings and drops only when it closes, and that is the one to reach for over carpet or an uneven floor where a fixed seal would drag. The 39 is cut to the leaf width on site and is fire rated per UL10c, so on a fire door over a flat threshold the fixed sweep is the straightforward call.
