Dual gas struts let one person lift the sash and hold it steady at the open angle, so counter staff can serve, take orders and hand food out without props or a second pair of hands, then pull it shut with the U-shaped handles.
The whole width of the frame clears when the sash lifts, leaving no vertical bar in the customer's sightline, so a street-facing wall turns into an open serving hatch that works as a pickup point, order window or bar top.
Slim aluminum alloy profiles and clear glass keep the elevation clean and easy to brand, while multi-line gaskets seal the sash against the frame to hold back wind-driven rain and street noise when the window is closed.
Made for cafes, bakeries, bars, restaurants and hotel lounges where guests sit indoors and on the pavement, the window opens up the front wall during service and closes back into a quiet glazed facade after hours.
Two U-shaped stainless steel handles at the bottom edge let staff lift and close the sash from either side of the counter, and the struts, top hinge set and gaskets are replaceable parts that keep the window in daily service.
