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.

High quality low profile keys, shaped just right for me.

The best of of both worlds. The low profile keys on my Keychron K4 HE makes my typing much easier with far less mistakes than with the original taller keys. I now have 2 full sets of keys, high and low profile in case I need to change it one day. The keys are very good quality and very easy to replace. They are not shine through but the lighter font on a dark key is very visible even if the backlighting is switched off

Excellent Build Quality

I haven’t had a chance to install or use the fan yet, but I’m very impressed with the quality. It feels well made, and the design looks great. Everything arrived in perfect condition, and I’m looking forward to seeing how it performs once it’s installed.

Great first impressions

Haven’t had a chance to use it on the field yet, but my first impression is very positive. The harness feels well made, the stitching looks solid, and it fits comfortably. It holds the pods securely and seems like it’ll do the job well. Looking forward to trying it out.
