Atrium Door Locks & Hardware | OEM Replacement Parts

OEM-Spec Atrium Lock and Hardware Replacement Parts

Atrium door systems require precision-matched hardware for proper operation and security. Whether servicing existing installations or stocking new builds, correct cylinder, lock, and handle selection ensures alignment with frame geometry and locking mechanism type. Hardware compatibility hinges on identifying your specific Atrium model line and locking configuration—single-point or multipoint—before ordering replacement components.

Identify Your Atrium Hardware by Lock Type and Configuration

Atrium manufactures both single-point mortise locks and multipoint systems across hinged and sliding door platforms. Locate the existing cylinder, handle set, or lock body to confirm whether you need replacement components for a shootbolt, roller, tongue, or hook latch mechanism. Cross-reference your model number and hardware type against our 59-SKU inventory to pull exact OEM-compatible parts.

Match Cylinder, Handle, and Latch Specifications to Your Frame

Atrium hardware uses standard Euro and American cylinder formats, but backplate geometry, spindle length, and latch projection vary by door type. Measure existing hardware or reference frame documentation to confirm PZ distance, backset, and cylinder length. Incorrect sizing prevents proper handle operation and latch engagement—verify dimensions before installation.
