Abstract
A flexible entry boot provides a fluid-tight fitting between a wall of a fluid containment region and a conduit passing through the wall. The flexible entry boot comprises a seal member disposed within the containment region and a screw securing plate attached to the seal member. A flexibly rigid, cylindrical hollow support sleeve has a degree of flexibility sufficient to allow for the insertion of the conduit at angles less than or equal to an angle normal to the fluid containment wall while maintaining a fluid-tight environment, the hollow sleeve having a first open end integrally attached to the seal member, the first open end having a central throughbore in fluid communication with the cylindrical hollow support sleeve, the hollow sleeve having a second open end, the first open end adapted to flexibly receive a conduit, and the second open end adapted to releasably hold the conduit in place. A mechanism is provided for releasably attaching the hollow support sleeve to the conduit. The entry boot further comprises a mechanism, extending outwardly from the containment region, for releasably attaching the seal member to the wall of the containment region.
