Abstract
A securement device includes a pair of plungers movable within a housing. The plungers act as quick lock mechanism to engage and secure a threaded rod (or other object) that passes into a hole that runs through the housing. The plungers are spring-biased to position themselves toward so as to provide a radially inward force, for example to engage a threaded rod or device in the through hole in the housing. A spring within the housing presses the plunger pieces toward a portion of the housing where the outer surfaces engage other surfaces to push the plungers inward. The device includes a disengagement feature or mechanism that is used to push the plunger pieces out of engagement with the threaded rod. The disengagement feature may include a disengagement tool, and may include wings, such as on the plungers or on carriers for the plungers, that protrude out of the housing.
