A panel for an overhead sectional door includes an exterior skin on an exterior-facing side of the panel and an interior skin on an interior-facing side of the panel that define a plenum. An insulating material is disposed in the plenum. An upper backer strut is disposed in the plenum proximate a top leading edge of the interior skin and extends across a full length of the panel. A lower backer strut is disposed in the plenum proximate a bottom leading edge of the panel and extends across a full length of the panel. The upper backer strut and the lower backer strut each include first and second strut legs extending into the plenum. The first and second strut legs are spaced from the exterior skin. Hardware is attached to the panel by fastening the hardware to one of the upper backer strut and the lower backer strut.

A frame rail for a movable barrier includes a top side, a bottom side, a front side, and a rear side. A first module connector is formed on the rear side. The first module connector extends continuously along a length of the frame rail and is configured to slidably receive a corresponding second module connector of a module. The frame rail has a continuous cross-section with the first module connector integrally formed with the top, bottom, front, and rear sides. One of the first or second module connectors comprises a groove and the other of the first or second module connectors comprises a tongue configured for receipt within the groove. The first module connector is configured to slidably receive the second module connector from a longitudinal end surface of the frame rail.

Disclosed is strut for a wind load door comprised of connected portions disposed at angles to one another. The strut comprises a mounting portion, the mounting portion including a fastener mechanism adapted to connect the strut to a panel of the door. The mounting portion is connected with a first oblique portion, a first edge of the first oblique portion connected with the mounting portion at a first edge of the mounting portion, the first oblique portion extending at a first angle with respect to the mounting portion. The mounting portion is connected with a leg portion, a first edge of the leg portion connected with the mounting portion at a second edge of the mounting portion, the leg portion extending at a second angle with respect to the mounting portion. The leg portion is connected with a web portion, a first edge of the web portion connected with a second edge of the leg portion, the web portion extending at a third angle from the leg portion. The web portion is connected with a second oblique portion, a first edge of the second oblique portion connected with a second edge of the web portion, the second oblique portion extending at a fourth angle from the web portion. The strut may include one or more ribs extending along a portion of the mounting portion and the leg portion.

A garage door roller assembly includes at least one track and a first panel and a second panel that are movable along the at least one track. The first panel and the second panel are connected by a hinge. The first panel and the second panel each have a first end portion including a planar surface, a recess defined in the planar surface, and a rail extending from a trough of the recess, the rail having a height that is less than a depth of the recess. A channel member is secured to the rail of the first panel. The channel member extends beyond the planar surface of the first panel and is configured to receive the rail of the second panel.

A panel for a sectional door, the panel comprising: (a) a front wall; (b) a rear wall; (c) a top edge; (d) a bottom edge; (e) two side edges; (f) a first mounting means for mounting the panel in a pair of first guide tracks, one of each said pair of first guide tracks located adjacent each of said side edges; (g) a first rigid reinforcement member extending between said top and bottom edges to reinforce said panel against deflection; and (h) a first non-rigid restraining member located between said side edges to restrict the deflection of the panel, wherein said first non-rigid restraining member defines a path that runs adjacent to or through said first rigid reinforcement member and comprises a second mounting means for anchoring said first non-rigid reinforcement member to an anchor point.

A panel for an overhead sectional door includes an exterior skin on an exterior-facing side of the panel and an interior skin on an interior-facing side of the panel that define a plenum. An insulating material is disposed in the plenum. An upper backer strut is disposed in the plenum proximate a top leading edge of the interior skin and extends across a full length of the panel. A lower backer strut is disposed in the plenum proximate a bottom leading edge of the panel and extends across a full length of the panel. The upper backer strut and the lower backer strut each include first and second strut legs extending into the plenum. The first and second strut legs are spaced from the exterior skin. Hardware is attached to the panel by fastening the hardware to one of the upper backer strut and the lower backer strut.

A door having a stabilization mechanism for a lock is provided. The door is suitable for a substrate carrier and includes a bottom plate, a cover and a limiting structure. The bottom plate and the cover define an accommodating space for accommodating a plurality of lock structures, each lock structure configured to move between an unlocked position and a locked position, an limiting structure is disposed between lock structure and the cover, and the limiting structure provides an elastic force corresponding to the displacement of the lock structures between the unlocked position and the locked position, such that the lock structures is maintained to move at a horizontal level under the elastic force. The structural design and configuration of the disclosure can prevent collision of substrate carrier or a problem of door drop resulted from the door falling to open/close smoothly.
