Series 300 Minimalist Multi-Slide Door

Series 300 Minimalist Multi-Slide Door

Dramatic views with expanded glass. The Series 300 Minimalist Multi-Slide Door offers the same smooth operation and hardware options as our classic doors, but innovative narrow interlocks provide a minimalist aesthetic with maximum daylight. Large panel sizes, fine lines, and energy efficient low-E, dual-pane glass offer a beautiful new way to minimize the boundaries between indoors and outdoors.
  • Narrow 1.125” sightlines at interlocks
  • Panels up to 12 feet tall (maximum 70 square feet)
  • Premium hardware and roller options
  • Concealed locking system
  • Expansive opening sizes



With our stainless steel ball bearing rollers, the Series 300 Minimalist Multi-Slide Door offers smooth operation. American Architectural Manufacturers Association (AAMA) certified, the 1.5” quad roller offers a reduced bottom rail sightline while ensuring even the heaviest panels are easily supported.

Sill Options

Water Barrier Sill

Designed for effectiveness in all climates, the water barrier sill’s 1.5″ interior leg and weep-hole system safeguards 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 300 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 actuator lock.
