What Makes It Different

Glides Over (Almost) Any Surface

A “floating” sill track insert gives the Series 3700 Vinyl Multi-Slide Door superior rolling performance, making it highly adaptable to a variety of flooring substrate conditions.

No Additional Framing Necessary

Designed to fit into most 2x4 and 2x6 openings, the three-panel configuration of the Series 3700 requires no additional framing.

Easier, More Economical Installation

Two nail fin set-back options, built into the profile as a standard offering, help make installation easier and faster.

Snap-In Interlock

Because the interlock is applied after the panel is installed, it can be cut so there are no gaps where unwanted air and light can get in.

Colored Hardware Options

For a consistent look, on doors with standard handles, we match the hardware color of the Series 3700 Vinyl Multi-Slide Doors to the frame. The two-piece flush handle with keyed lock is available with black hardware only.

Product Features

Integrated Weep System

Designed for effectiveness in a variety of climates, an integrated weep system safeguards against water intrusion, eliminating the need for a hard sill pan in most applications. Sill height is 1.5”.

Climate-Ready Glass

For better energy performance, our multi-slide doors feature low-E dual-pane, argon-filled glass from Cardinal IG. Pre-applied Cardinal Preserve film protects glass during installation.

Clean Design

Designed to complement nearly any space, the Series 3700 features big glass and a narrow profile to allow for more light and bigger views.

Tested for Performance

Western Window Systems products are subjected to air, water, and structural testing and are AAMA- and NFRC-tested and certified. Access our current NFRC values here.

Energy Efficient

The Series 3700 is designed to meet prescriptive energy codes in a variety of climates and features Energy Star-qualified options.

Concealed Locking System

The Series 3700 Vinyl Multi-Slide Door includes a hidden multi-point lock to secure its large sliding panels, providing additional strength and protection. A keyed cylinder option is available.

Flush-Mounted Handle

The narrow design of the Series 3700’s flush-mounted handle (available with black hardware only) allows panels to easily slide past each other.
