Our products GritBlockerAccess cover keyways filled with debris can lead to incorrect lifting of a manhole covers out of the ground, creating a health and safety risk. Fixing this can take time and can be potentially dangerous to operatives. GritBlocker is the solution! An anti-blockage keyway insert which simply fits into the manhole cover keyway preventing debris from blocking the opening and allows a lifting key to be inserted. ![]() The problem![]() Manhole lid keyway pockets are often filled with debris which prevents the insertion of lifting key equipment to such an extent that operatives attempt other unsafe methods of lid removal. A long time can be wasted on site by operatives attempting to clear keyways enough to allow key insertion, particularly where covers have not been accessed for some time. The solution![]() We have solved this common issue with a simple, but effective remedy: An anti-blockage keyway insert which fills the lid keyway pocket with a material prevents detrimental debris ingress, but allows the insertion and rotation of a lifting key.
