Abstract: A flexible penetration fitting is provided for sealing the hole through which a pipeline penetrates a wall of an underground containment box. The penetration fitting includes a flexible boot with a sealing flange for providing a first seal against the inside wall of the box. The sealing flange is held against the wall by a backing ring placed against the outside wall of the box. The backing ring includes a plurality of studs extending through the wall and into the box. A compression ring with a plurality of holes is placed over the sealing flange with the studs of the backing ring extending though the holes. A plurality of nuts are threaded to the studs to hold the sealing flange firmly against the inside wall of the box. The flexible boot also includes a sleeve for providing a second seal against the outside surface of the pipeline. The sleeve is stepped with different sized openings so as to be able to receive different sizes of pipelines.

Abstract: A device to assist in the opening of a manhole cover has a biasing member such as a spring and a pivot rod or rods. The rods and spring are each pivotably attached to first and second mounting brackets. The first mounting bracket is attached to a skirt for seating the manhole cover and the second mounting bracket is attached to the underside of the cover. The spring acts to rotate the manhole cover in a reverse direction to which the cover is intended to be opened until the cover contacts the rod or rods. Then, the cover is rotated in an opposite direction, preferably with manual assistance, using the rods as pivot arms.
