Floor-to-ceiling multi-slide doors completely open this home to the patio and lake the house sits on.
A 90-degree, stacking multi-slide door opens the corner of the master bedroom to the patio and landscape.


Sealed stainless-steel ball bearing rollers make the Series 600 Multi-Slide Door easy to operate. An interlocking track design provides structural integrity and makes it possible to span wide openings with almost any number of panels. Rolling hardware is AAMA certified and includes two options — a standard 1.81″ size and a 3″ Monster Roller capable of handling more than twice the weight of the largest panel.

Series 600 Multi-Slide Door

The Door That’s a Window Too

Featuring the same rolling glass panels that stack or slide into pockets as our multi-slide door, the Series 600 Multi-Slide Window is a head-turning alternative to a standard opening. Perfect for large, long areas where people congregate.

Sill Options

Water Barrier Sill

A weep system and an interior leg available in different pressure ratings and sizes (1.5″, 2″, and 2.6″ for various performance requirements) helps safeguard against water intrusion. For additional protection, the back leg of each sliding panel penetrates the track to help keep out dust and debris. .

Series 600 Multi-Slide Flush Sill

Flush Sill

When ease of entry is more important than performance against the elements, our flush sill is the perfect choice. With an interior and exterior sill height of just 0.75″, it lines up with most interior flooring for a smooth transition to the outside. Weep holes in the track allow water to drain away from the door while the back leg of each sliding panel keeps out dust and debris by penetrating the track. Not warrantied against water penetration.
Thinline Sill

Thinline Sill

The ability of our signature thinline sill to disappear almost completely makes it ideal for projects where a continuation of flooring from the inside to the outside needs to appear virtually seamless. Staggered tracks expose a slim channel on which the panels roll with the finished flooring installed between them. Not warrantied against water penetration.

Handles and Locking

Flush-Mounted Handle

The flush-mounted handle’s clean and narrow design allows panels to easily slide past each other or into a pocket. Available in brushed nickel or black.

Concealed Locking System

The Series 600 Multi-Slide Door includes a hidden stainless-steel multi-point lock to secure its large sliding panels, providing additional strength and protection. Handles come with a keyed lock.

Premium Handle

Our premium handle features a minimal design, comfortable grip, and the option of keyed lock that allows the door to be unlocked from the exterior. Available in brushed nickel or black. Not available on pocketing multi-slide door systems, angled doors, or with lead screens.
