24 Vdc gear motor, with built-in control unit, adjustable speed and anti-crush safety function. Two types of case available, galvanized steel or stainless steel (AISI 304) in three sizes from 3 to 7 metres long. More comfort and safety in programming and maintenance phases: The same built-in control unit is used on all versions, and is installed in the bottom part of the barrier body. Large front door for quick and easy access. Easily-removable reinforced gear motor support. Maximum safety: when both opening and closing; barrier body supports on the inside for minimum visual impact. Electronically-adjustable speed from 3.5" (Wide M) to 5" (Wide L) for fast opening. Sturdiness, reliability and easy installation: elliptical section bar for lighter weight and higher wind-gust resistance; special profile for fast assembly of the accessories. Optional pivot joint to protect the barrier in the event of collision. The bar can be assembled either on the right or left. Easy to balance, thanks to practical spring tension adjustment. No black out: operation is guaranteed in the event of power outages by the PS234 backup battery installed inside the control unit. Release with triangular key protected against the weather.
