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.

Centurion Regulator for solar backup

Lets start by adding this might not be a cheap chinese product, hence the price. it is a tested and thoroughly thought through plain and simple regulator, works on solar panel that I bought at 18v 80W and churns out power as a backup to the battery in the centurion gate motor. you know you need a backup on a backup these days :)

Then the supplier is efficient, communication at each point of the purchase steps, making my experience a breeze. Product bubble wrapped and boxed up with a speedy delivery and supporting invoice. Appreciate it!

Stylish and Great Value

The Black Bamboo Tumbler has a clean, modern look that suits most contemporary bathrooms. The matte black finish pairs nicely with the natural bamboo base, giving it a stylish, minimalist appearance. It’s lightweight and works well as a toothbrush holder or rinsing cup.

Perfect product exactly as advertised.

Perfect product, it fit perfectly into to my cz75 p07 CO2 pistol and this setup even turned my non Blowback into a Blowback pistol. It will work on the ASG STI duty one aswell as they use the same internal.
