Installation Instructions for
The Sentinel Bi-fold Door Stop™ Patent Pending
The Bi-fold Sentinel™ is designed to prevent damage to bi-fold doors and the hardware components. The Sentinel protects the top pivot bracket and pins by absorbing the impact of the door opening. The Sentinel protects the track channel and pins by preventing rotation of the open door when the door handle is pulled in the wrong direction. The Sentinel works with the most common bifold hardware systems. The Bifold doors and hardware should be in good working order, or repaired if needed before installing the Sentinel.

2 The door should be in the open position. Use the spacer clips while positioning to allow a small gap between the Sentinel and the door stiles. Hold the Sentinel against the door stiles, making sure the base is not tilted.
Install the two screws (1) through the slotted holes as shown. Remove the spacer clips. Open and close the door gently. Adjust the Sentinel position if needed, so that it does not obstruct the door.

4 The pivot pin brace provides additional protection when there is no decorative molding in front of the track.
The brace is hooked around the pivot pin, and then folded around the Sentinel wall as shown. It is helpful to mark the brace against the Sentinel before folding to 90 degrees with pliers. Finish bending the brace around the Sentinel wall with pliers, or Channellocks.
It is also possible to bend the brace in situ by hand, but the brace may not be tight enough to function properly. The clip can be removed and reused several times.
The brace should not pull hard on the pivot pin. The door may bind if the brace is too tight.
