Toe and Heeling a Bifolding Door


This guide provides a detailed explanation of how we suggest to toe and heel our doors. This is for use as a guide only as each set of doors are unique and may require different levels of packing in the toe and heeling process (amount of packers used). Please use your own judgment and if unsure please contact an experienced installer or our technical department.


The red sections display where to toe and heel on a 3 panel door all one way.

The yellow sections display the final fix packer position.

Start by toe and heeling the panel attached to the frame first and work towards the traffic door (Or slave door). 

Packers are supplied in a range of sizes which are colour coded for ease of use. Packers used in this guide are an example only. Each door is unique and will require different levels of packing. Always use a range of packers to best suit the door being toe and heeled.

When toe and heeling use a glazing shovel where needed.

  1. Place 2-3 packers at the bottom of the door on the hinge side. (number of packers depends on door tolerances) 
  1. Place glazed unit into door frame.
  1. Pack the top of the unit on the handle side of the door. Use a variety of packers until the glazed unit sits firm in place.
  1. Pack the side of the unit on the handle side of the door. Use a variety of packers until the glazed unit sits firm in place and square within the frame.
  1. Pack the side of the unit on the hinge side of the door. Use a variety of packers until glazed unit sits firm in place and square within the frame.
  1. Lastly pack the top side corner on the hinge side of the door. Use a variety of packers until the glazed unit sits firm in place. This will help keep the glazed unit square and in place.
  1. Check door is completely level with the outer frame. If not add or remove packers where needed.
  1. Once all panels have been toe and heeled check door is running correctly and that the locking system works correctly. 
  1. If required silicone the packers on the uprights of the door into place. (this will prevent the packers from moving).
  1. Finally clip bead into place.
