Why choose the DL4100/26D?

When your application demands more than simple keypad access — when you need hundreds or thousands of users, audit-trail visibility, timed schedules and a true privacy/lock-out mode (e.g., for restrooms, on-call rooms, healthcare zones, executive suites) — the DL4100 offers enterprise-level capability in a standalone form. With satin chrome aesthetics, field-reversible installation and top-tier durability, it’s suited to schools, hospitals, corporate facilities, retail flagships, and any high-traffic door needing a robust electronic access solution.
