ESP Aperta Surface Strike Door Lock: This fail-secure surface-mount rim strike lock is engineered from robust aluminium alloy with a corrosion-resistant brushed-silver finish, ensuring both aesthetic appeal and long-term durability. It operates on a non-polarised 12 V DC input drawing just 240 mA and delivers an impressive 400 kg holding force for secure access control. Designed for compatibility with Yale-type surface locks, the unit features a compact 32 × 110 mm profile and operates reliably over a temperature range of –20 DegreeC to +50 DegreeC. A flush-mount version is also available, and the lock carries a three-year warranty backed by ESP’s technical support network.
