Expandable frames eliminate the need for custom-built frames by being able to accommodate a range of wall thicknesses and uneven conditions.

Assembly Options

3-Piece Knock Down Frame

Shipped knocked down (KD) in three separate pieces: two adjustable jambs and a telescoping header. Each component is designed to slide and interlock with the others, allowing the frame to expand or contract to match the wall thickness on-site.

Key Features

Adjustable Wall Fit

Allows on-site flexibility to compensate for uneven drywall, framing irregularities, or out-of-plumb conditions, ensuring a proper door fit.

Quick & Easy Installation

Ships knocked down in three pieces and assembles on-site without welding, saving time on labour and material handling.

Clean, Professional Finish

Provides a flush, uniform appearance with telescoping components that conceal adjustment points when properly installed.

Versatile Application

Ideal for both new construction and retrofit projects, especially where wall dimensions vary or are uncertain.

Frame Profile Options

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.

Frames must be removed from any wrapping or covering and be stored in a protected location in an upright position, on wood sills or planks.
All frames must be set plumb, square and level at the correct elevation. Fire-labelled frames must be installed in accordance with NFPA 80, most current edition.
