The Retrofit Fire Door Kit made by Ever Ready Closures, based in Concord, Ontario, has won the Best New Canadian Product at the 2001 Canadian Hardware and Building Materials show. The Retrofit Fire Door Kit is a hardware device that converts any existing non-rated door — even a 1-3/8″ hollow core door — into a 20 minute fire-rated one. The kit includes a preformed steel facing, with a ceramic-based fire retardant material attached to one side. The material is similar to that used in tiles in the Space Shuttle and prevents transmission of up to 3,000 degrees F through the door. Listed with Underwriters Laboratories of Canada (ULC) the door kit can be fitted in 30 minutes without special tools. Applications include basement apartments, hotels, motels, dormitories, military housing, schools, offices, hospitals, etc. It is ideal for historical preservation since the kit installs on one side of the door, leaving the hallway aesthetics unchanged.

Cornell Iron Works has added features to its rolling fire doors and counter fire doors. The M100 FireGard system for large doors and doors with coils recessed in soffits or above ceilings is reset at the touch of a button after testing or power failure. The FireGard EZ Test ‘n Set rolling fire door is chain operated to eliminate the need for field wiring and to lower initial costs. It can be tested and reset by throwing a lever mounted at floor level. Both the M100 and the EZ Test ‘n Set systems have governors that reliably control closing speeds.

The SmokeShield smoke-and-draft control assembly has UL labelling for openings up to 12 wide by 10 high, such as exist in healthcare facilities, schools, industrial, commercial and public spaces.
