The ST 500 has been developed for commercial use in doors up to a wing length of maximum 5.0 m. The extremely robust mechanics combined with the modern and powerful control equipment make the ST 500 an optimum solution for commercial use. The operator that is completely made of metal and the high-quality bronze spindle arm provide reliable operation with a duty cycle of up to 80 %. Thus, wings of up to a maximum weight of 600 kg are no problem for the ST 500.
