Single-Unit Double-Door Interlocking Pass Box | Stainless Steel Cleanroom Transfer Window | Cleanroom Grade

Two Doors. One Open at a Time. Zero Cross-Contamination: Single-Unit Double-Door Interlocking Pass Boxes

The Single-Unit Double-Door Interlocking Pass Box is the transfer solution for GMP cleanrooms, operating theatres, and laboratories — a self-contained stainless pass box whose double doors interlock so only one can be opened at a time, letting items pass between a clean zone and a non-clean area without opening a direct air path between them. With a smooth crevice-free interior that cleans down easily, sealed doors, and a viewing window to see the contents before opening, it keeps the pressure and cleanliness boundary intact through every transfer. It is the dependable pass box for pharmaceutical plants, hospital clean areas, electronics cleanrooms, and laboratories.
