The INOX CX Series redefines commercial door security by marrying industrial robustness with a refined, modern aesthetic. Crafted as a Grade 1 heavy-duty deadbolt, CX delivers uncompromising strength in every component — from its solid brass body and reinforced internal mechanism to its anti-torque housing and saw-resistant core. Its refined design language gives it a sleek presence on the door, and the range of available finishes—from satin chrome to CeraMax coatings—ensures it can complement architectural styles while providing formidable protection. Whether for institutional, corporate, or high-traffic installations, the CX Series offers a serious, built-to-last deadbolt solution that stands strong behind any entrance.
