A deadbolt assembly for securing co-mounted doors together and activating at least one deadbolt may include at least a first retention component and a first actuator interface mounted to or defined by a first coupling assembly of a key-side assembly operatively mounted to one of the co-mounted doors, and at least a second retention component and a second actuator interface mounted to or defined by a second coupling assembly of a lever-side assembly operatively mounted to the other of the co-mounted doors, at least one of the key-side assembly and the lever-side assembly including a deadbolt assembly having a deadbolt configured to be responsive to actuation thereof to extend a deadbolt therefrom, wherein actuation of the deadbolt assembly also causes the first and second retention components to secure the first and second coupling assemblies to one another.

Deadbolt assembly for simultaneously securing co-mounted doors together and actuating at least one deadbolt

A retention assembly secures together field-coupled handle assemblies of co-mounted doors and may include a first retention component mounted to or defined by a first magnet housing of a first door handle assembly operatively mounted to one of the co-mounted doors, and a second retention component mounted to or defined by a second magnet housing of a second door handle assembly operatively mounted to the other of the co-mounted doors, the first and second magnet housings arranged such that magnets carried by each align with and magnetically couple to one another and such that the first retention component aligns with the second retention component and mechanically couple to one another as the first and second door handle assemblies are brought into contact with each other.

Retention assembly for securing together coupled handle assemblies of co-mounted doors

A door system including a primary door molding attachable to a primary door frame, the primary door molding including a first vertical member and a first hinge member extending from the first vertical member. One of a horizontal member from which the first vertical member downwardly extends and the first vertical member includes a first rotatably engageable element, and the first hinge member includes a second rotatably engageable element vertically spaced from the first rotatably engageable element.

Door-ready molding

Building systems including a frame with a horizontal member from which first and second vertical bars downwardly extend and a panel attached to the frame. The building systems include at least one of an integrated fastener cover that is moveable to a closed position that covers a portion of a fastener, a gusset assembly with a junction cover positioned at a corner junction between two adjacent portions of a panel, and hinge assemblies that reduce the sagging of a panel, such as a door.

Building systems and methods for installing building systems relative to building openings

Ready-to-install door systems comprising, prior to installation, a door, a hinge-side z-bar, a drip cap, and a latch-side z-bar, all connected. In addition, the system may comprise door closer hardware attached to the door and either the drip cap or the hinge-side z-bar; an installation notch; or screw holders. Screw holders are also provided. Methods of installing the present door systems are also provided.

Ready to install door system

This disclosure is generally directed to a hydraulic door closer, and more specifically is directed to a hydraulic storm or screen door closer that has a fluid overflow chamber providing fluid volume and pressure control for both expanded and contracted fluid at different temperatures. The disclosed hydraulic door closer comprises a fluid overflow chamber adapted to hold sufficient fluid to maintain required operating fluid or oil levels at different temperatures, and to ensure proper closer performance under both extreme high and low temperature conditions.

Hydraulic door closer with fluid overflow chamber

The present disclosure describes various embodiments of a concealed or hidden door closer that is installed in a rail of a door assembly. In some embodiments, the door frame and door closer components are configured to allow the door assembly to be readily installed as either a left or a right hand hinged door.

Door with hidden door closer

The present disclosure describes various embodiments of a concealed or hidden door closer that is installed in a drip cap of a door assembly. In some embodiments, the door frame and door closer components are configured to allow the door assembly to be readily installed as either a left or a right hand hinged door.
