A fenestration assembly includes an operator assembly having an escutcheon configured for coupling with the fenestration assembly. A handle linkage is coupled with the escutcheon and rotatable relative to the escutcheon. The handle linkage includes a handle arm rotatably coupled with the escutcheon and a handle knob rotatably coupled with the handle arm. An articulating joint is between the handle arm and the handle knob. The handle linkage is movable between stowed and operational configurations. In the stowed configuration the handle linkage is seated along the escutcheon, and the handle arm and the handle knob are aligned. In the operational configuration the handle linkage is unseated from the escutcheon, the handle knob and the handle arm are misaligned with the handle knob at an operating angle relative to the handle arm, and the handle linkage is configured to open and close a fenestration panel.

A hatch power lift and locking system may include a hatch configured to cover an opening, the hatch being pivotable about an axis between a closed position and an open position. The assembly may also include at least one latch dog attached to the hatch, and at least one dog catch pin engaging with the at least one latch dog in the closed position. The at least one latch dog may include a latch slot for receiving the at least one dog catch pin, and a latch catch for engaging the at least one dog catch pin. The assembly may further include an actuator configured to move at least a portion of the hatch between the closed position and the open position.

A roof support system includes a support member configured to be mounted between a roof panel and a frame of an enclosure. The support member is movable to an extended position that supports the roof panel in an open position. A cam lock mechanism is operatively connected to the support member for releasably locking the support member in the extended position. In the extended position, a pin of the support member is received within a slot of the cam lock mechanism such that engagement of the pin with a closed end of the slot prevents the support member from moving from the extended position toward a retracted position. The cam lock mechanism includes a cam configured to rotate to a locking position that at least partially blocks an open end of the slot such that the pin of the support member is prevented from backing out of the slot.

A composite sash and frame for windows and doors uses a sash assembly, a frame head, a frame sill and a frame jamb to thermally maximize structural integrity, prevent thermal transfer, and increase aesthetic appeal. The composite sash and frame for windows and doors uses a two-sided system. The first side is constructed from rigid durable materials that are designed to withstand corrosion and is positioned on the exterior surface of a building. The second side is constructed from aesthetically appealing thermally isolating materials and is positioned on the interior surface of the building. The sash assembly, the frame head, the frame sill, and the frame jamb are all constructed using this two-sided architecture, and are thus specifically designed to withstand corrosion and damage while satisfying the user's aesthetic requirements.

An anti-tilting transmission mechanism for doors and windows includes a first fixed plate, a second fixed plate, a transmission gear located between the first fixed plate and the second fixed plate, and a transmission rack, wherein: two guide though-holes are respectively provided on two ends of the second fixed plate; two threaded columns, which are capable of moving back and forth, are respectively located within the guide though-holes; two limit ribs are respectively located at an outer edge of a rear end of the threaded columns; two compression springs are respectively located between the first fixed plate and the threaded columns; each of the threaded columns has a threaded hole axially provided thereon, so that after passing through a door and window profile, screws are respectively tightened with the threaded holes on the threaded columns, so as to fix the transmission mechanism onto the door and window profile.
