Access 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.
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.
We have solved this common issue with a simple, but effective remedy: An anti-blockage keyway insert which fills the lid keyway pocket. Gritblocker prevents detrimental debris ingress, but allows the insertion and rotation of a lifting key.
