The electrical cover comprises a friction-held electrical cover for a recessed light fixture. Embodiments of the electrical cover described herein provide flexible finish material covers that guard recessed can light fixtures from paint, spackling, and other foreign materials. The frictionally-held finish material covers utilize specifically shaped features on the surfaces, such as negative draft, that contact the electrical components to increase the hold on the electrical device. Some of the shaped features of the frictionally-held covers also help minimize stress in the cover. Features are also molded into the parts to assist and strengthen the cover once installed, and thus protect against the intrusion of finish material behind the cover.

The electrical cover comprises a press-fit or other type of fastener held electrical cover. Embodiments of the electrical cover described herein provide flexible finish material covers that guard light switches from paint, spackling, and other foreign materials. The covers utilize specifically shaped features on the surfaces that help minimize stress in the cover. The fasteners used to hold the light electrical covers are specifically designed to accommodate variations in manufacturers threaded hole positions and diameter tolerances. The electrical covers are shaped with an arched rear surface that assists in minimizing edge warping when the electrical cover is positioned against the wall surface. Features are also molded into the parts to assist and strengthen the cover flatness once installed, and thus protect against the intrusion of finish material behind the cover.

The present invention provides a wheel spraying device, comprising a frame, an electric motor, a hollow shaft, a ring flange, and cylinders. During use of the device, the need of jacking up and rotating a wheel in wheel spraying can be met, and the difficulty of removing the protection plugs of bolt hole due to thickening and clogging after completion of spraying can be completely avoided. Meanwhile, the device has the characteristics of simple structure, convenience for use, low manufacturing cost, and safe and stable performance.

A selective wall sealing system disclosed herein comprises a wall and a sealing member. The wall comprises one or more portions for utility elements, and the sealing member is configured to seal and secure the portions of utility elements from external contact when the maintenance activity is performed on the wall. In an embodiment, an adhesive is applied along the contour of the portion of the utility element, and the section of the sealing member outside the contour is cut away to allow a user to perform maintenance activity on the rest of the wall. In an embodiment, the sealing member is peeled off after the maintenance activity is performed on the wall. In an embodiment, the utility element is an electrical utility. In an embodiment, the sealing member is a sheet member. In an embodiment, the sealing member is made of paper, plastic, cardboard or posterboard.

An apparatus includes a container holding a whitening material, and a dispenser to release the whitening material from the container, wherein the dispenser is configured to simultaneously dispense the whitening material in a spray pattern 360 degrees around the dispenser.

A system and method for painting a component (3) of a vehicle brake (1) includes a sealing plug (7) inserted into a recess (5), the recess extending in the direction of a longitudinal axis (L) and which has an inner face (9) which is intended to be kept free from paint. The method includes providing the component (3) and introducing a sealing plug (7) into the recess (5) of the component. The sealing plug (7) has at least one sealing face (11a-11h) and the sealing face (11a-11h) is disposed inside the recess (5). The sealing face is moved into sealing abutment with the inner face (9) in a radial direction. The method includes painting the component (3) after the sealing plug (7) has been introduced. The sealing plug blocks paint from being deposited on the inner face.

A masking member includes: a masking main body that is formed of an elastic material and that closes an opening portion of a hollow member by being inserted into the opening portion; and a passage portion that is formed at the masking main body, that opens on an outer peripheral surface of the masking main body, and that connects an outside and an inside of the hollow member by at least a part of an opening at the outer peripheral surface being exposed to the outside of the hollow member in a case in which the masking main body, in a state of closing the opening portion, moves in a direction opposite from an insertion direction.
