One frame, many walls

The frame carries the door, the hinges and the strike – and it is the part that must suit the wall. WS frames are double-rabbet profiles in galvannealed steel with 5/8 in stops, made to the wall thickness and fitted with the anchor for the wall type.

Prefinished frames

Prefinished frames are hot-dip galvanized steel with a polyurethane finish applied in the factory. They slip over the finished, painted wall and take snap-on casings in steel, aluminium or stainless steel – no site painting, installation in about 15 minutes, and an adjustable version for walls from 3¾ in to 9⅛ in.

  • 18 or 20 gauge hot-dip galvanized steel, door holding equal to a 16 gauge one-piece frame
  • Standard and custom colours, brushed or bright stainless casings
  • Reversible hardware locations – no handing for 6'8" doors
  • Matching sidelights and borrowed lights

Reinforcement

  • Hinges: 7 gauge reinforcement, universal 4½ in preparation
  • Strike: heavy-duty reinforcement, ASA strike prep
  • Closer: 14 gauge reinforcement
  • Silencers, grout guards and spreaders fitted as standard

Frequently asked questions

Knock-down or welded frames?

Knock-down frames ship flat and are assembled on site – ideal for drywall and export. Welded frames arrive in one piece, are stiffer and are preferred for masonry walls and heavy-traffic openings.

Can a frame be fixed to an existing opening?

Yes – existing-opening anchors bolt the frame through the soffit into finished concrete or masonry.
