The Role of Rackmount Enclosures
Lansing’s GrayBox A-, B-, and P-Style enclosures are engineered for seamless integration into standard 19” rack systems. Precision-formed panels and mounting ears ensure a clean, secure fit within rack frames, while the rigid aluminum construction provides strength and thermal stability. Modular front and rear panels allow for easy customization and service access, making these enclosures ideal for instrumentation, control, and test system builds.
