Blanke DIBA RKM (drain collar)
The BLANKE DIBA RKM (drain collar) is a special design of a punched sleeve, similar to BLANKE DIBA BM/WM (floor/wall pipe sleeves), but with a deepdrawn collar. This collar ensures an effective and safe connection of the waterproofing system (for example BLANKE DIBA 100) with drainage tubes. The drain collar can either be used as an interior collar (BLANKE DIBA RKM DN 50-IA) or an exterior collar (BLANKE DIBA RKM DN 50 AA) for drains. The collar dimensions are adapted to the following standard sizes: DN 50/DN 70/DN 100).
