Features

Reinforced Section Design

Universal 224 sections are manufactured from hot-dipped galvanized steel and built with reinforced meeting rails that enhance door stiffness. This helps the door feel stable and dependable through frequent open-and-close cycles.

Built for Strong, Steady Operation

Wide-body galvanized hinges, quality track and torsion components, and nylon rollers support smooth travel. Optional upgrades are available for heavier-use needs or more demanding operating conditions.

Classic Style Choices for Curb Appeal

Select Short Panel or Long Panel raised embossments for a traditional look, or choose a Flush design for a cleaner, more modern appearance. The rotary-embossed woodgrain texture adds depth and visual character.

Upgrade Path for Comfort and Appearance

Universal 224 supports window designs and decorative hardware for a more customized look. If comfort and noise reduction are priorities, insulation options can be added with a durable backskin.
