Abstract
A re-enterable environmentally sealed enclosure for housing circuitry and/or cable components of a communication network employs a removable cover attached to an enclosure base by a pivoting cam-tracking system. The tracking configuration positions the cover in a manner that, as it approaches the enclosure base when being closed, a seal located in the cover is evenly compressed along its entire perimeter against a corresponding mating surface on the base, thereby distributing the compressive force equally across the entire seal, with any shear forces substantially eliminated. A single tensioning system is provided adjacent the cam-tracking system, so that the tracking system does not operate as a counter-lever to the tensioning system, and visa versa, thereby improving the distribution of force across the seal.
