With an aluminium profile and a one-piece aluminium casting lid, the famous Cristal range combines elegant lines and extreme sturdiness. Available in a wide variety of sizes, it includes small hatches particularly suitable for ventilation purpose, and larger models that make excellent storage lockers. The hinges are equipped with friction, coupled with a compensating spring on large sizes (49.49, 61.61 et 79.79) that allows the lid to be held open in any position up to 90° (maximum opening 180°).
