In industrial architecture, sliding doors have special demands: The doors and gates that are often heavy require sliding door fittings that are able to satisfy their requirements. This is where the Apoll sliding door fitting comes into play, which can handle door weights of up to 600 kg, depending on the variant. Its single and double roller carriages distribute the load optimally and – particularly important for large, heavy doors – the steel or plastic rollers ensure that the door runs particularly smoothly.
