Q

Can I choose which way the doors open?

Choose the opening direct before installing the frame. The door set is reversible with left or right opening. The doors always open outwards.

Q

How do I fix the frame head to the lintel in the case of a steal header?

  • Fixings must fix through the aluminium track, timber frame head and lintel. The fold and slide system is "top hung" so all the weight is supported from the aluminium top channel and the head of the timber frame, hence the importance of a secure fixing into the lintel, to enable the system to work correctly.
  • For fixing into RSJ / "I" lintel use nuts and bolts (not provided).
  • Direct frame fixings are provided to fix to a steel lintel.
  • If in any doubt consult a structural engineer.

Choose the opening direct before installing the frame. The door set is reversible with left or right opening. The doors always open outwards.
