1. A security door system for mounting in a door opening, comprising:
- a pair of identical guide tracks for vertical installation as door guide members on both sides of a door, each of said identical guide tracks being universally mountable to encompass either side edge of said door opening;
a pair of identical plate support brackets for installation onto the top of said guide tracks, each of said plate support brackets being universally mountable onto a guide track on either side of the door opening, said plate support brackets extending above the top edge of the door opening;
a pair of identical support plates for installation onto said plate support brackets to be supported thereby, each of said support plates being universally mountable onto a plate support bracket on either side of the door opening, said support plates extending inwardly from the top of the door opening;
a barrel assembly horizontally, rotatably mounted on said support plates; and
a roll-up door mounted at the top thereof to and supported by said barrel assembly, said roll-up door being positionable to cover said door opening with the side edges of said roll-up door being retained by said guide tracks, said roll-up door being rolled about said barrel assembly as the door is raised, wherein each of said support plates has a circular aperture therein at the end of said support plates away from said plate support brackets, and said system additionally comprises;
a pair of U-shaped axle support brackets each having a notch therein which notch extends throughout the curved section of said U-shaped support bracket and up much of the length of the legs of said U-shaped support bracket, said notch in one of said U-shaped support brackets fitting over the top edge of each said support plate, said curved section of said U-shaped support brackets being concentric with and slightly smaller in diameter than said circular aperture in each of said support plates, said support plates each having means therein for retaining one of said U-shaped support brackets in position thereon.

Abstract
A roll-up or curtain type door is disclosed which has modular components which are interchangeable for use on either side of the door, thereby reducing significantly the number of parts which must be manufactured for the door. The number of hardware items is also reduced significantly by designing components which slide together in a secure locking fashion, resulting in better ease of assembly and installation. In one embodiment, the roll-up door of the present invention is used to secure a storage unit with shelves.
