You asked, we listened. In addition to being our most economical solution to differentiate your homes through indoor-outdoor living, the Series 3700 Vinyl Multi-Slide Door addresses key operating mechanisms while also managing to enhance the installation process. With special features such as a “floating” track insert, integral nail fins, and a snap-in interlock, the Series 3700 rolls with ease while helping to make installation easier on your bottom line.
So whether you’re designing a moving glass wall system into a single-family home community, townhouse, or condo, the Series 3700 Vinyl Multi-Slide Door is your passageway between a great idea and a great result.

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.

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.
