4550 SERIES VARI-SLIDE™ DOORS

The 4550 series Vari-Slide™ automatic sliding glass door system from Monumental Windows and Doors is thermally broken and custom-designed for multiple large telescoping panels—exactly what you need for that distinct California look and feel.

Contemporary design is all about narrow profiles, clean lines, and flush finishes. You’ll love the concealed Slim-Trac™ that lands right on trend. The Vari-Slide retractable sliding doors are designed with options for pocketing and stacking. System configuration options are endless! Anything is possible for your custom project.

Each system is custom-built using semi-automated fabricating equipment for numerous configurations—including 90- & 135-degree units with options for motorization. Unlimited configurations also including pocketing and slide-by setups. Our newly designed flush pulls and latch assembly are made of aircraft quality precision-milled stainless steel, with a large actuator for finger- touch operation. The maximum security laminated hook-lock is an industry standard and has been used for years by commercial door manufacturers to meet strict forced-entry requirements.

Flush Sill

Our standard flush sill is just 1" tall and is designed to line up evenly with interior flooring, creating a level transition to the outdoors. Move seamlessly between indoor and outdoor spaces in any luxury home.

Slim-Trac™

Our concealed Slim-Trac™ is available for interior applications, and can be used in exterior applications as well where air and water infiltration and wind loading is not a concern. 1" floor tracks are installed to be flush with stone or concrete flooring, and staggered for better concealment while panels are closed. The panels are fully weather-stripped around the base.
