The Nib Nobbler allows you to maintain channel continuity when nibs or build outs are constructed. Typically, they obstruct channels and create drainage problems and if gaps are left pedestrian inevitably fall into them! When no provision is made flooding often occurs.
The cost of gullies is huge and there are not always sewers to receive the water. Blackburn & Roberts now provide the answer with the Nib Nobbler. This is a duct which is built into the obstruction and provides channel continuity through it. These unobtrusive units provide a cost effective alternative to gullies.
