Important Information and Disclaimers

Fire Rated Frames
Fire-labelled frames will be provided for those openings requiring fire protection ratings, as determined and scheduled by the architect. Such products have been tested in strict conformance with CAN4-S104, ASTM E152 or NFPA 252 as listed by a nationally recognized agency having a factory inspection service, in conjunction with the Canadian Steel Door Manufacturers Association, and will be constructed as detailed in the follow–up service procedures.
Frames will be blanked, reinforced, drilled and tapped for mortised template hardware. Mortised cut-outs will be protected with steel guard boxes (may be omitted on drywall applications). Frames will be reinforced, where required, for surface-mounted hardware. Drilling and tapping are to be done by others in the field, at the time of installation. Frames will be prepared for single stud rubber door silencers, three (3) per single door openings.
Unless specified otherwise the location of hinges, strikes and closer reinforcing will be All Steel Doors 2000 standard locations.

  • Secure anchors and connections to adjacent construction.
  • Brace frames rigidly in position while building in.
  • Remove temporary bars prior to installation.
  • Install wood spreaders at three points on frame rebate to maintain frame width.
  • Provide vertical support at the centre of head for openings exceeding 48” in width.
