When installing a mini roll-up door, first measure the rough opening and determine bracket mounting surface areas. Position the door, install the brackets, set the initial spring tension, and install roll-up door stop clips.
Always check the roll-up door for any visible signs of damage before starting to install it. While installing the door, secure both brackets to the jambs so they fit securely into the structure. Avoid welding the guides to the jambs. Always make adjustments to the springs with the door fully opened. Use door stop clips; failure to do so may cause the door to travel beyond the guides and cause injury.
