Alluser C1 – Cylindrical Security Portal

The Alluser C1 is the most compact cylindrical security portal in the Alluser product range, designed to provide controlled, high-security pedestrian access in environments with space constraints. With an external diameter of just 988 mm and a clear opening of 600 mm, it is the ideal solution for wall-mounted or corridor installations while maintaining the highest security standards.
