CHAINS ARE THE BEST SYSTEM FOR LIFTING THE MONOBLOCK DOOR
Iron chains seem silent and light when they are new; however, with time and usage, if they are not frequently oiled, they will start to squeak and moving them will become more difficult, and there is a possibility that they may break. Certified steel cables, used in the Palazzetti hearth doors, do not require maintenance, they are more silent, and they operate without noises or squeaks, even after months of inactivity. Their resistance over time has been tested with rigorous and prolonged testing, performed while the fireplace was running.
This device has been used to lift and lower the door tens of thousands of times, demonstrating that cables are more resistant than other lifting methods (ex. Chains).
