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.

Keep those pesky monkeys at bay.

Exactly what was hopeing for. Looks nice and feels really solid. The blanks are very loud. The holster is just rite for the model I did not have to cut it. If you have the money and need to scare off some critters while wild camping; get a blank gun and some pepper rounds you will not be disappointed.

First off, my first time buying from Gunmansa, and as an avid online shopper, it was a breeze with very good prices and great payment and delivery options. Delivery was also really fast considering the recent floods in the Cape area.

Ive been holding out to upgrade from AM4 to AM5, but with the RAM crises going on, i decided to rather upgrade my old Ryzen 5 3600 to this 5600XT, and honestly it is a huge diffrance in performance, stability, temprature and its boost is so much more stable along with much higher clocks. so im glad i took this path and my old AM4 system will ride along with me for a good couple more years.

Such a smooth buying experience.

I purchased an air rifle combo and the buying experience was so smooth and the duration from purchase to delivered was a mere 3 days.
Rifle was well packaged for good protection.
Very pleased with this shop.
