A sliding and pivoting fenestration unit, such as a sliding door, with screen. Embodiments of the fenestration unit include a locking and height-adjustable pivot rider, a head slide, a screen carrier, and a method of operation.

Systems and method for shimming fenestration units configured to be set into a rough opening of a building structure or wall. The fenestration units may include a shimming assembly coupled to a frame and including a carrier portion and an adjustment portion. The carrier portion may have an upper carrier surface defining at least one pawl extending away from the upper carrier surface and a lower carrier surface having a contact feature configured to be received within a channel of the frame. The adjustment portion may define a plurality of teeth and is configured to slide longitudinally along the carrier portion such that the at least one pawl is configured to slide along the plurality of teeth until a desired level of shimming is reached, at which point the carrier member and the adjustment member are locked in position.

A fenestration unit fenestration unit includes a frame having a receiver channel. The fenestration unit further includes an installation fin having a pedestal portion and a projecting portion extending from the pedestal portion. The pedestal portion has a cam insert receivable in each of a first undercut and a second undercut of the receiver channel, a clip insert receivable in each of the first undercut and the second undercut, the pedestal portion including a retention catch. The projecting portion has a body and a retention protrusion receivable in the retention catch for securing the projecting portion in an upright position. The installation fin is reversibly couplable to the frame with the projecting portion extending in an interior direction in a first configuration of a prone position and with the projecting portion extending in an exterior direction in a second configuration of the prone position.

Installation systems and methods for fenestration units configured to be set into a rough opening (RO) from interior side of a building structure or wall. The fenestration units may include a retention system coupled to the frame and operable to exert a retention force on the fenestration unit to maintain positive engagement of the fenestration unit with the rough opening framing and resist extraction of the fenestration unit from the rough opening upon insertion of the fenestration unit in the rough opening from the interior side of the rough opening.

A fluid dispensing system includes a housing, an inertial measurement unit supported by the housing and operable to sense linear and rotational acceleration of the housing, a nozzle supported by the housing operable to expel a fluid, a pressure source in fluid communication with the housing and the nozzle and operable to pressurize the fluid, a valve positioned fluidically upstream from the nozzle and operable to regulate fluid flow to the nozzle, and a controller in operable to receive an application value relating to a predetermined volume of fluid to be applied to a surface of an article, to receive movement data relating to the linear and rotational acceleration of the housing sensed by the inertial measurement unit, and to regulate the valve based on the movement data and the application value.

A fenestration unit is configured for installation in a rough opening in a structure defined by rough opening framing. The fenestration unit includes a frame including a channel and a first mounting bracket. The first mounting bracket includes a first leg and an interlocking cam coupled to the first leg. The interlocking cam is configured to be received in the channel of the frame, and the interlocking cam is pivotable from an unlocked configuration to a locked configuration. In the unlocked configuration, the interlocking cam permits detachment of the first mounting bracket from the frame, and in the locked configuration the interlocking cam secures the first mounting bracket to the frame. The first mounting bracket further includes a second leg coupled to the first leg. The second leg is angularly offset from the first leg and is configured to abut an interior face of the rough opening framing.

Sash carriers mounted to the sides of a sash support the sash in a window frame for sliding movement between sliding closed and sliding open positions. Balance springs on the sash carriers counterbalance the weight of the sash during the sliding movement. The sash can be mounted to the sash carriers for tilting movement between tilt closed and tilt open positions. Brakes on the sash carriers are actuated by the sash when the sash is moved to the tilt open position, and inhibit sliding movement of the sash carriers and sash when the sash is in the tilt open position.

A screen channel insert for use in connection with a fenestration unit frame including a spline channel. The screen channel insert includes a frame attachment portion for attaching the screen channel insert to the spline channel of the fenestration unit frame, and a channel portion defining an insert spline channel. The insert spline channel is configured to receive a spline to secure a screen to the screen channel insert. The insert spline channel can have different sizes than the spline channel of the frame, enabling the frame to be used with screens having different thicknesses.
