42" x 96" Commercial Hollow Metal Doors – Knock-Down Frame Assembly, Premium Insulated Packages

For projects requiring a taller, wider commercial steel door with uncompromising durability and performance, our 42" x 96" commercial hollow metal door packages are the perfect solution. Each package combines a USA-made galvannealed steel door with a precision-engineered knock-down (KD) frame for quick, accurate on-site installation.

Built for demanding commercial, industrial, and institutional environments, these doors feature a premium insulated polystyrene core that delivers superior thermal efficiency, sound reduction, and a solid, high-quality feel. Unlike low-cost imports, our doors are manufactured in America for long-term reliability and professional-grade performance.

The KD frame ships in three pieces for lower freight costs and easier handling, then assembles in minutes with a precise, secure fit. Prepped for standard commercial hardware, this package is ideal for high-traffic openings in schools, hospitals, offices, warehouses, and public buildings.
