LORO-X Series 84 DRAINLET gravity flow with standard hood
The LORO-X DRAINLET® main drainage and emergency drainage with gravity flow are characterized by space-saving dimensions without a "pot" in the roof area and a high drainage through the powerful LORO-X hood with ventilation openings. They are suitable for flat roofs as warm, cold and inverted roofs, for green roofs, trafficable roof surfaces and trapezoidal sheet metal roofs, as well as for box gutters.
LORO-X DRAINJET for siphonic flow can be found here.
Clamping flange for bitumen and plastic
The clamping flange as a loose and fixed flange construction is equally suitable for sealing sheets (drain) and vapor barriers (2-piece) made of bitumen and plastic.
