Specifically designed to meet the needs of automatic pedestrian entrances. The wide range of solutions makes the aluminium frames perfect for installing in any architectural context: they can be tailor-made in the most varied configurations and colours and can be fitted with devices which, in the case of an emergency, permit immediate push-opening with the slightest of pressure. To optimise space and have the widest through passage, all the aluminium frames in the ALU and PAM Series have a telescopic opening system.
