Open visualizer →Why Choose the LIFT 100 Series?
Fold the wall. Open the bar. The LIFT 100 Series Fold-Up Window turns an ordinary opening into a wide-open pass-through. The top-hinged sash folds upward in one smooth motion and holds at any height — fully open for a true indoor-outdoor counter, half open for ventilation, or anywhere in between. Order it with a bottom frame for a traditional window installation — or specify the no-bottom-frame version and run your countertop straight through the opening for a true indoor-outdoor bar.
- Effortless fold-up operation — heavy-duty hardware stops and holds at any height
- With or without bottom frame — flush pass-through or classic window install
- Retractable screen keeps bugs out while the breeze comes in — unobstructed view when not in use
- 1.72 mm aluminum alloy profiles with composite film layer for corrosion resistance
System design
Engineered to fold
01
Effortless Fold-Up Operation
The heavy-duty folding hardware raises the top-hinged sash smoothly and holds it at any height — fully open for a pass-through counter, partially open for ventilation, or fully closed. No cranks, no stays, no slamming.
02
Durable Ergonomic Handle
A robust handle makes the folding sash effortless to lift and pull, and the panels stop exactly where you leave them — customized ventilation for any season or occasion.
03
Retractable Screen — Available
A roll-up screen cassette spans the full opening and lowers into place when the sash is open — ventilation without the bugs, and an unobstructed view when not in use.
04
Built to Last
1.72 mm aluminum alloy profiles with a composite film layer deliver corrosion resistance and weather protection, finished in a durable powder coat.
05
Quiet, Weathertight Closure
High-quality weather strips work with the frame construction for quiet, weathertight performance — and the top-hinged design sheds rain even when the window is open.
06
Pass-Through Configurations
Choose the with-bottom-frame version for a traditional install with a finished interior ledge — or the no-bottom-frame version for a flush, floor-of-opening pass-through that runs your countertop straight through the wall.
