Automatic Window


This is the same basic unit as model SS-4035E, however, we build a custom transom over the top which extends the height to 52”.

This window comes standard with a 15” reduced service opening, electronic auto-lock and a nighttime lock bar for maximum security. We can make these units any height required. Model IFSST-4035E comes fully glazed with 5/8” clear insulated glass.

SST-4860E / IFT-4860

SST-4860E / IFT-4860E – Speed of service is the key. Models SST-4860E and insulated model IFT-4860E offer exceptional speed and reliability. This unit is perfect for any application demanding hands-free speedy service.

This unit features a built in air curtain to meet certain health code requirements. We can also offer this unit with restricted openings for our California customers. The non-heated air curtain is mounted outside while the heated air curtain is mounted inside.

Self-Closing Window


These windows are manual opening, self closing sliders with auto locking handles. You can also take advantage of the magnet hold open device: Slide the window to it’s full stop and a magnet will hold it open. Once your customer leaves, tap the window and it will close and lock automatically.This combination unit is great for areas with insect problems or health codes requiring an air curtain (fly fan) in conjunction with your drive-thru window.
