Multiple Sliding Door
The Aluminum Multiple Sliding Door expands openings with stacked, side-by-side panels that glide on precision tracks. Slim, thermally broken frames keep sightlines narrow and views wide while supporting energy-efficient patio doors performance. Choose multi-sliding or pocket configurations to clear wall space and connect indoor rooms to patios and courtyards. Durable anodized finishes resist heat and corrosion for long service life with low maintenance.
Key Benefits
- 20 micron anodizing thickness provides long-lasting finish and consistent color.
- Frame and panels are mechanically fastened for additional support, and structural integrity.
- 6-1/2” jamb width
- Reinforcement in larger size doors ensures additional structural stability for oversize capabilities
- Four wheel bearing rollers in stainless steel casing are standard. The bearings provide for an exceptionally smooth slide, and their exceptional engineering allows these rollers to hold and slide the heavier door panels.
- Argon gas filled chambers for low heat transference.
- Optional SuperSpacer with a secondary butyl seal provides a secure IG seal

Retrofit Frame
Ideal for replacement projects. The replacement flange allows installation without breaking out stucco, shortening timelines and reducing mess.


Block Frame
Designed for replacement openings where a nailing fin is not required. An optional sloped sill adapter improves drainage and fit.
Nail-On Frame
Best for new construction. The nailing fin enables precise placement in newly framed openings and supports a reliable weather seal behind exterior finishes.

Multiple-Sliding and Pocket Door Styles
Multi-sliding doors come in several panel counts and stacking directions. Pocket styles allow panels to slide into a wall pocket so the opening is fully clear.
How to read the codes (exterior view, left to right):
- MTS = multi-sliding
- MTP = multi-sliding pocket
- X = operable sliding panel
- O = fixed panel
Example: MTS-OXX = a multi-sliding door where the left panel is fixed and the two right panels slide behind it.
Pocket doors add L or R to show the pocket side.
