Door Type

[dik]

I'm trying to determine the name of an industrial fire rated door. It is almost archaic and is/was located in some old industrial buildings.

The manner of construction was prescribed and it could provide a 2 hour or more FRR. It was recognised by one of the Building Codes in Canada, the NFPA or FM Global; I don't recall, now.

It was fabricated from sheet metal material and was often suspended on rollers and overhead channel track, with gravity closure and a metal bracket at the closure end to prevent it from being 'pushed' open and to provide a seal. It sometimes had pulleys and a 'bucket' counterbalance to assist opening.

Can anyone recall the name of this door assembly?

dik...doesn't ring a bell. Have you contacted Warnock Hersey? They rated most of these doors.

I've seen what you describe many times, but can't recall the manufacturer either.
