  • Features

    • Maximum Thermal Protection - Energy-saving polyurethane foam insulation is used to deliver exceptional R-values.
    • Rugged Hardware and Springs - The ThermaSeal TM300 door comes packaged with the right combination of long-lasting hardware, track, and springs to precisely match your door’s size and application.
    • Reduced Airflow - Dual vinyl barriers dramatically reduce air infiltration. A true thermal break prevents heat loss and eliminates any metal-to-metal contact between surfaces.
    • Decreased Energy Costs - Raynor ThermaSeal TM300 doors help you reduce energy costs with a u-shaped, vinyl bottom weather seal and sturdy aluminum retainer.
    • Choice of Windows - Select either 24″ x 8″ (shown), 24″ x 12″, or 34″ x 16″. Raynor ThermaSeal TM300 doors are also available with aluminum full view window sections. Choose from a variety of insulated glass, acrylic, tempered, and polycarbonate styles to suit any application.
    • High-cycle Counterbalance Systems - For reliable operation in high-traffic areas, choose high-cycle torsion springs with 25,000, 50,000, or 100,000-cycle life.* For reduced maintenance and ultra-smooth operation in heavy-use applications, choose a weight counterbalance system. *Some options may be limited to door size or model.
    • Customized Track and Hardware Systems - Track systems are supplied to fit special clearances, inclines, or contour applications. Hardware and track systems can be designed to fit any need. Additional trussing is available for special wind loading applications. A QuikClip™ pre-assembled track option is also available.
    • Secure Locks - In applications where control and access are important, choose from a variety of locking options to help keep your building secure. Locks come in both inside and outside variations.
    • Carbon Monoxide Vent - This allows you to channel fumes to the outside when the door is closed. Available in a variety of sizes.
    • Removable Center Posts - Carry-away and swing-up options are available for extra-wide openings. Ideal for agricultural or airplane hangar applications.
    • Pass Door - Pass doors conserve energy by allowing entry door access without the full operation of the garage door and minimize wear and tear by conserving cycle life. Some options may be limited to door size or model.
