An extension spring overhead door system (10) in which the spring (22) may be quickly and easily placed in tension with the door (21) in a closed position. A spring tensioning device (30, 140) is provided which eliminates the need for multiple installers to lift the full weight of the door (21) and then clamp or otherwise prop the door (21) in an open position. An extension spring containment tube (84) is also provided which surrounds the entire periphery of the spring (22) to fully contain the entire length of the extension spring (22). A second embodiment of the spring tensioning device (140) allows mounting of device (140) on either side of the door (21) while retaining easy access.

Système à ressort d'extension (10) pour porte basculante, dans lequel le ressort (22) peut être rapidement et aisément mis sous tension lorsque la porte (21) se trouve en position fermée. Un dispositif de mise sous tension (30, 140) du ressort permet de se passer de plusieurs monteurs pour soulever tout le poids de la porte (21) puis retenir ou soutenir la porte (21) en position ouverte. Un tube de confinement (84) du ressort d'allongement entoure toute la périphérie du ressort (22) dans toute sa longueur. Un second mode de réalisation du dispositif tendeur (140) du ressort permet de monter ce dispositif (140) d'un côté ou de l'autre de la porte (21) sans en affecter l'accès.
