<p>The present invention relates to a roller door track for guiding a roller door curtain of a roller door assembly. The present invention provides a roller door track at least in part having a U-shape configuration in transverse cross section comprising a base web and two opposed side walls upstanding from the base web to define a recess adapted to slidably receive a side edge of a roller door curtain of a roller door therewithin, wherein one of the side walls includes a blunted free edge opposite the base web. The invention is particularly, though not exclusively, suited for use as a track for guiding a roller door curtain, such as a garage roller door curtain, wherein the track is secured to walls adjacent an opening into a structure, such as a garage or shed, and in use the track receives the laterally opposite side edges of the roller door curtain and guides the roller door curtain through movement between open and closed positions. 2,5 / 53 Fig. 2</p> |
