H: /gl/Intenvoven/NRPortbl/DCC/LGL/5859814_I.doc-3/12/2013 -12 Abstract A brace 1 is provided for use with a door. The door includes door panels 2 coupled to guides 6 using guide wheels 4. The brace 1 is attached to one of the guides 6 and an engaging portion 9 of the brace 1 is located contiguous to the door. In the event of a normal loading condition the engaging portion is not in contact with the door. In the event of deflection of the door during wind or other loading the engaging portion 9 contacts the door and prevents further deformation of the door. [Fig. 14] - 8/9 Fig 17. Fig 18.
