Manhole seals are designed to have flexibility which allows for slight movement by pedestrians and traffic. These seals are the perfect solution for covering manholes, drains, external tool and utility boxes and any rough surface.
If an attempt is made to remove them they will deform the seal itself, making it obvious that tampering has occurred. The increased flexibility of these security seals, make them suitable for uneven or unstable surfaces with excellent resistance to adverse environmental conditions.
