Yes. Each retractable stairs has a detailed instructions sheet to guide you during all phases of assembly. Do not modify or disassemble the stairs without authorisation from the manufacturer. Inclination of the open stairs must not be less than 65° to the ground. During installation, ensure that the hatch is perfectly levelled (0° PANTO, 4Pz, TERRACE, or 90° WALL, PALCO) in order to avoid faulty functioning of the opening and closing mechanisms of the loft ladder.
