Abstract

A device including a housing having an access opening, a swing arm mounted to the housing and configured to be selectively pivoted toward and away from the access opening, and a closure captured by the swing arm. The closure can be configured to be selectively moved in a substantially vertical motion relative to the swing arm between a retracted position and an inserted position at least partially in the access opening and can have locking features for cooperating with engagement features in the device to move the closure into a closed and sealed configuration.
