DD overflow grille 60 cm sales pack

DD Ultraflow overflow comb

The comb has both vertical and horizontal drain slots, which allow around 30-50% more flow (compared to standard drains).
This prevents high water levels or even overflowing of the pool.
Adjustable between 6-8mm and 10mm glass by folding the strut.
The comb is easily removable for cleaning and has a very high flow rate.
