The 200 Series is a non-thermal commercial entrance door with a 1¾ inch door depth, built around a narrow 2⅛ inch vertical stile and designed for projects where a slimmer sightline is preferred without giving up commercial-grade durability. It is fabricated with a Heavy Duty Slide-in Interlocking corner block, which keeps the door square and rigid over years of daily use. Horizontal member options of 4 inch, 7 inch or 9½ inch support the visual and functional requirements of the entrance, with single or dual glazed glass infill available depending on the project's glazing requirements.
300 Series Medium Stile Non-Thermal Door
A stronger visual profile for high-traffic entrances
Shares the same non-thermal construction as the 200 Series, but steps up to a wider 3¾ inch medium stile for a bolder, more substantial visual profile suited to heavier daily traffic.
- 3¾″ medium vertical stiles
- Horizontal member options: 4″, 7″ or 9½″
- Fabricated with Heavy Duty Slide-in Interlocking corner block
- Single or dual glazed glass infill
Clear Anodized, Dark Bronze Anodized and Mill Finish are standard. Custom painted colors are available and require additional lead time.

The 300 Series shares the same 1¾ inch door depth and non-thermal construction as the 200 Series — a Heavy Duty Slide-in Interlocking corner block, single or dual glazed glass infill and 4 inch, 7 inch or 9½ inch horizontal member options — but steps up to a wider 3¾ inch medium stile for a bolder, more substantial visual profile. That added presence makes it well suited to entrances that see heavier daily traffic or where the design calls for a stronger frame line at the door.

The 400T is a thermally broken entrance door with a 3½ inch (89 mm) medium stile, 4 inch (102 mm), 7½ inch (191 mm) or 10 inch (254 mm) horizontal member options, and a 2¼ inch (57 mm) door depth. It accepts the documented 1 inch double- or 1½ inch triple-glazed configurations. The available QAI report and thermal simulation contain results for defined specimens, glass, hardware and conditions; displayed U-values and physical test results must be matched to that configuration and must not be treated as universal installed performance. Confirm the proposed door, surrounding framing, hardware, anchors, perimeter seals, applicable code and project conditions with current documentation.
