Framing Components for Sliding Doors

Framing Components for Sliding Doors product line gives you a true “Build on Site” sliding door solution that just uses self drilling fasteners (Tek screws) and a drill (or impact driver) to build a door frame. Simply add your “Trimdek” sheet facing panels and you have a sturdy, and structurally sound, sliding door that will provide years of service.

All items are made from steel with a very high degree of corrosion resistance built in. We recommend using Class 3 or Class 4 coated fasteners to give you the best long term protection against corrosion on all penetrations or joins.

Calculating the required components

Framing Components for Sliding Doors


Use the following information will help with calculating component lengths.

TRACK POSITION = Top of Opening to Underside of Door Track: 75mm

DOOR HEIGHT “A”
Underside of door track to floor level less 75mm


DOOR WIDTH “B”
Width of opening plus 30mm (min) for
overlap each end (B+60mm total width
any number of doors on a single track)







EF4 PERIMETER FRAMING
Vertical Members (door sides) = Measurement “A” minus 65mm
Horizontal Members (top & bottom) = Measurement “B” minus 65mm
EB2 BACKING RAIL
Horizontal Cladding Braces = Measurement “B” minus 10mm
Fix at 1800mm (max) spacings when used with 0.49mm Trimdek or similar profile claddings

Carriage Mounting Blocks at least 100mm in length
Fix carriages 500mm (min) to 750mm (max) from door ends (Link to Carriages)
Door Push Rails – optional = approx 1000mm
Cladding Length = A – 70mm

  • Fitting of the Angle Braces at approx 45 degrees will give the correct
    positioning for the Carriage Mounting Blocks.
  • We recommend fitting a full length EB2 Horizontal Brace inserted to the
    bottom EF4 horizontal member to strengthen the bottom of the door frame.
  • Intermediate EB2 Horizontal Braces should be fitted at even spacings
    between top & bottom frame. Doors up to 2.6m high one only; 2.6 to 4.8m
    two braces; doors over 4.8m high minimum three braces.
