A compression connector for securing an apparatus to a mounting surface. The compression connector device can include a housing that can include a cavity configured to accept a wedge member within the cavity. The wedge member and cavity can include corresponding angular surfaces. A biasing means can be coupled to the wedge member or housing and configured to move the wedge member from a first position to a second position within the cavity. As the wedge member is moved to a second position a compressive force can be applied between the wedge and a mounting surface of an object.

A paint roller sleeve removal tool for overlying an unwanted roller sleeve to allow a user to remove a soiled roller sleeve without spreading mess undesirably. The paint roller sleeve removal tool includes a primary tubular member having a first primary panel hingedly affixed to a second primary panel. The secondary tubular member is affixed to the primary tubular member, the secondary tubular member having a first secondary panel is affixed to a distal end of the first primary panel and a second secondary panel is affixed to a distal end of the second primary panel. The paint roller sleeve removal tool includes a plurality of protrusions that are affixed to an interior surface of each of the first primary panel, the second primary panel, the first secondary panel, and the second secondary panel.

A method of using a meter puller for installing and removing an electrical power meter comprising a sleeve member adapted for sliding movement about the meter and having a first end opposite a second end, a latching mechanism for securing the meter puller to the meter, and a shield secured to the second end of the sleeve member. The shield includes two sides, wherein the meter puller is positioned on a first side of the shield. A handle is positioned on an opposite second side of the shield and operatively connected to the latching mechanism.
