    摘要: Fitting that is compatible with standard fittings is described. In one embodiment, the end of one of a matched set of fittings is provided with an elastomeric material. The elastomeric material deforms when the matched fittings are coupled, resulting in a reduced volume. In certain embodiments, a tube is provided through the tube which is attached at a proximal end and extends to the distal end of the elastomeric material. When the fitting are coupled the tube protrudes past the end of the elastomeric material and into the coupled fitting. In certain embodiments the fitting otherwise conforms to International Standard ISO 594.

    摘要: A manhole guard, methods of assembling the same, and methods of using the same, are described. The manhole guard generally includes a plurality of sections connected for movement, the sections being capable of being locked into a fixed rigid structure through the use of a first arm and second arm that act independently of each other. The manhole guard can include attachable mounting brackets designed to facilitate the attachment of a hoist device and/or winch.
