The Alluser HPJ140 is the first half-security portal, originally invented and patented by Alluser. With its distinctive half-moon shape, it set the standard later imitated in the market, and remains the reference solution for secure retrofitting of existing swing or sliding doors.
The HPJ140 creates a highly secure, anti-tailgating entrance while maintaining a compact external footprint. Equipped with ultrasonic APD sensors, it prevents multiple persons from entering together, ensuring maximum security without compromising usability. With a 900 mm portal entrance and an internal width of 1220 mm, it is ideal for buildings with limited space or where side access must be preserved.
Certified up to RC3 and RC4 (EN 1627) and LPS1175 (A1, B3), the HPJ140 is widely used in sensitive infrastructures, data centres, embassies, banks, and other high-security environments.
