The Ready Access 275 Series 47.5" drive-thru window is a robust, cost-effective solution designed for demanding commercial environments, including restaurants, healthcare facilities, and ticketing kiosks. Featuring a left-to-right sliding operable panel (from the exterior view) paired with a fixed panel, this window delivers high visibility while ensuring durability. The clear 1/4-inch tempered glass and clear anodized aluminum frame resist rust, pitting, and weathering, making it ideal for outdoor and high-traffic applications. With a patented gravity-based self-closing mechanism, this window offers a smooth, user-friendly experience while maintaining security with self-latching, thumb turn lock, and night locking bar features. The header-mounted operating design eliminates the bottom sill track, simplifying cleaning and drainage, while the angled bottom sill ensures proper exterior drainage. Fully assembled and pre-glazed, this window is easy to install and maintain, saving time and labor costs. Whether you're outfitting a drive-thru lane, walk-up window, or service counter, the Ready Access 275 Series delivers performance, security, and longevity for commercial operations.
