Our strongest and most energy-efficient design ever.
Western Window Systems

Product Type

Exterior doors

Embodying nearly 60 years of advancements in multi-slide door design, the Series 7600 is packed with innovations that address energy and structural requirements. Of course, the design elements that have made it a favorite with architects — thin profiles and large, unobstructed rolling glass panels that stack or slide into pockets — are still unmistakable.

A .30 U-value for standard, low-E, argon-filled dual-pane glass makes the Series 7600 able to deliver energy efficiency in a variety of weather conditions. And because it’s available in the most sizes and configurations of any brand, there are infinite ways to customize.

Energy Efficiency

To deliver energy efficiency in a variety of weather conditions, the Series 7600 has a .30 U-value for standard, low-E, argon-filled dual-pane glass. Plus, it’s compliant with California’s rigorous Title 24 requirements in both the prescriptive and performance methods.

Climate-Ready Class

The Series 7600 comes standard with Cardinal IG’s all climate coated or high-performance glass that delivers solar control and high visibility. Glass can be customized in a variety of types, colors, and thicknesses and includes options such as laminated glass, solar- and glare-control glass, enhanced winter performance glass, and Neat low-maintenance glass. Pre-applied Cardinal Preserve film protects glass through installation.

Bigger Sizes

Offering some of the biggest sizes of any brand, the Series 7600 is available in heights up to 15 feet in most markets. Choose from pocketing, non-pocketing, and bi-parting configurations. There’s even a 90-degree option that completely opens up the sides of a room by eliminating a connecting post.

Clean Design

An interlock stile with a narrow 2.9” width keeps lines clean and glass big.

Smooth Operation

Sealed stainless steel ball bearing rollers make our aluminum multi-slide doors easy to operate. An interlocking track design provides structural integrity and makes it possible to span wide openings with almost any number of panels.

Concealed Locking System

The Series 7600 includes a hidden stainless steel multi-point lock to secure its large sliding panels, providing additional strength and protection. A keyed cylinder option is available.

Heavy Duty Hardware

Rolling hardware includes two options: a standard 1.81” size and our signature Quad-Zilla Roller, capable of handling extreme panel sizes and heavy glass types.

Tested for Durability

The Series 7600 Multi-Slide Door features a design pressure (DP) rating of 50 and is certified by the NFRC and AAMA.
