The doorLink 3650 Flush Panel delivers a clean, unadorned aesthetic that suits contemporary and modern-style homes across the OKC metro. Behind its smooth, flat face lies the same 26-gauge 3-layer sandwich construction and R-10.25 CFC-free polystyrene insulation as the rest of the 3600 series — paired with eight deep woodgrain color options and the exclusively compatible Contemporary Window Frame for homes that call for a sleek, minimalist look. Available in widths up to 24 feet, the 3650 handles the full range of single, double, and oversized openings DOORTEC installs throughout Oklahoma City, Edmond, Norman, Moore, Yukon, and beyond.

Hot dipped galvanized steel construction with hemmed inside return rail provides superior strength and durability.
Includes 0.25 mil rust inhibiting primer and 0.75 mil exterior topcoat that resists fading and chalking, while providing consistent color from panel to panel and more durability.
Galvanized steel hinge plates run the full height of each section at all hinge locations to facilitate the attachment of hinges, handles, struts, and step plates.
For superior strength and better sealing against wind, rain, and snow.
Provides added strength while securing replaceable U-type bottom astragal weatherstrip to help keep the elements out.
Sandwich type construction with polystyrene insulation pressure bonded between two sheets of hot dipped galvanized steel enhances your home's energy savings, makes your door operation quieter, and reduces exterior noise in your garage.
Environmentally friendly insulation that will not degrade with vibration or time.
The doorLink 3650 Flush Panel is available in eight deep woodgrain prefinished colors. The flush panel profile gives the woodgrain texture a continuous, uninterrupted surface — a distinctly different look from the carriage and grooved-panel models. Colors may vary from actual product.
*Colors may vary from actual product. DOORTEC can provide physical color samples — contact us before finalizing your selection.
The doorLink 3650 is compatible with the Contemporary Window Frame — a modern, slim-profile insert designed specifically for the 3650 and Ozark 3700 series. Not all glazing options may be available from all distributors. Contact your supplier for window options.

The doorLink 3650 Flush Panel sets itself apart from the rest of the doorLink lineup by eliminating raised panels, grooves, and carriage details entirely — leaving a smooth, flat surface with deep woodgrain texture across the full door face. This makes the 3650 particularly well suited for homes with clean-line architecture, flat-roof designs, or modern farmhouse aesthetics that have become increasingly popular in new construction across Oklahoma City, Edmond, and the broader OKC metro. The same 26-gauge 3-layer sandwich construction and R-10.25 CFC-free polystyrene insulation found throughout the 3600 series means the 3650 delivers energy efficiency and noise reduction without any compromise on the modern look. DOORTEC is an authorized doorLink dealer — call (405) 720-7107 for a free quote.
Two features make the 3650 stand out on the DOORTEC floor. First, it is the only doorLink residential model compatible with the Contemporary Window Frame — a slim 41”×7” insert with a Black exterior and White interior frame, designed specifically for the flush and Ozark 3700 panel profiles. Glass tints include Clear, Satin, and GreyLite 31. Second, the 3650 is available up to 24 feet wide, a full 2 feet wider than the 3630 and 3640 carriage models — covering the RV bays, three-car tandem openings, and commercial-adjacent residential applications that appear across Norman, Moore, Yukon, Midwest City, Guthrie, El Reno, and Tulsa.
