Enquire for more details

The LK20 Electric Strike - Pre-impulse is a high-performance access control solution designed for secure and reliable door entry systems. Engineered with a pre-impulse mechanism, it ensures swift, low-power operation while maintaining durability for high-traffic environments. Ideal for commercial buildings, offices, and restricted access areas, this strike offers seamless integration with most access control systems, including card readers and keypads.

Constructed from hardened steel, the LK20 provides exceptional resistance to forced entry and tampering. Its compact design allows for easy installation in standard door frames, minimizing retrofit challenges. The pre-impulse technology reduces power consumption, making it an energy-efficient choice for continuous operation without compromising security.

With fail-safe and fail-secure operation modes, the LK20 adapts to your security needs—whether ensuring door release during emergencies or maintaining lockdown when power is lost. Its silent operation and smooth latch engagement enhance user experience while meeting stringent security standards.

I bought the Snug Lite 1-Port Home Charger with Type-C Cable (2.1A) in January 2026. The delivery was fast, and the charger is still working perfectly.

If the product is imported, delivery may take longer. However, if it’s a local product, delivery is usually much faster. I'm happy with their service.

Great point and fire training pistol.

No doubt powerful, well made. No slide action, but the MOS makes up for that. Shoots like a dream.
