heroal RD 55

Narrow Profile for Small Barrel Diameter

The roll-formed heroal RD 55 SL is a slim roller door slat that winds particularly tightly for clear widths of up to 3.500 mm. For a maximum curtain height of 3.000 mm the barrel diameter takes up around 230 mm on an octagonal axle with a diameter of 70 mm and is therefore suitable for box sizes of as little as 230 mm.
