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.
Color-Matched Hardware
For a consistent look, we match the hardware color of the Series 3700 Vinyl Multi-Slide Door to the frame. For our black capstock option, black hardware is used.

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”. Standard aluminum sill covers enhance durability.
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.

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 allows panels to easily slide past each other.
