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. At Monumental Windows and Doors, we understand that every home is unique and has different design needs. That's why we offer custom projects that provide flexibility and elegance to homeowners. Our team of experts works closely with clients to create custom designs that fit their specific styles and preferences. Whether it's a modern or traditional look, we can bring any vision to life for your luxury home.
Our custom projects not only provide flexibility in design but also in functionality. We can create custom finishes for thermally broken windows and doors that are tailored to the specific needs of each room in a home, such as increased ventilation, an all-encompassing view, or energy efficiency. With our wide range of materials, colors, and finishes, homeowners can truly personalize their space while enhancing its overall aesthetic appeal. Monumental is committed to delivering high-quality products that meet the unique needs of each client while providing unmatched elegance and durability.
Each 4550 series Vari-Slide™ automatic sliding glass door system is custom-built using semi-automated fabricating equipment for numerous configurations — including 90- & 135-degree units with options for motorization. Unlimited configurations also include pocketing and slide-by setups. Our newly designed flush pulls and latch assembly is 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.

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.
