SDC
SDC (Security Door Controls), headquartered in Camarillo, California since 1969, engineers American-made electric strikes, magnetic locks, and delayed egress hardware for commercial access control. SDC is specified where integrators need U.S.-based engineering, domestic manufacturing, and specialized hardware for code-compliant egress (delayed egress), healthcare, and retrofit applications.
We stock the full SDC catalog — 1580 and 55 series electric strikes, MagForce 1581/1581LL/1582 magnetic locks, DELAY 100/1511 delayed egress locks for code-compliant emergency exit control, UniLock universal strike retrofit, ExitCheck exit alarm retrofits, and the full SDC power supply line — at authorized SDC dealer pricing. Every product ships with SDC's 5-year limited warranty and access to U.S.-based technical support, and our access control engineers help with delayed egress code compliance (NFPA 101, IBC), fail-safe vs fail-secure specification, and magnetic lock holding-force sizing for the specific door weight and environmental conditions.
No bots, just experts
