Abstract
The clamping band is used to clamp a connector boot within a hole in a manhole riser or other generally cylindrical structure, particularly where the depth of the hole is greater than the thickness of the manhole riser. The clamping band has a width such that a portion of the band extends beyond the hole surface. The clamping band preferably overhangs both the inner surface and outer surface of the generally cylindrical wall of the manhole riser. In one embodiment, the clamping band is used to affect a pipe-to-manhole connection.
