A stackable shield removably insertable in an opening to an interior of a recessed light fixture receptacle is disclosed. The unit is characterized by a v-shaped divider structure defined by first and second divider walls extending between opposite parts of the outer wall. Configuration of the outer wall is alterable by urging the divider walls toward one another.

A wheel spraying protection device is composed of a hollow mounting rack, an electric cylinder, a tray, an electromagnetic chuck, a sleeve, a piston, a soft rubber cover, a support column, an end cover, high temperature resistant plastic protective plugs, springs and iron posts. The device can play a role in protecting during a wheel spraying process, and solves the problem that a flange face, a center hole and bolt hole conical surfaces are adhered with paint. The device has the characteristics of advanced process, easiness in manufacturing, simple structure, strong function and the like.

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.

A method for masking cooling passages of a turbine component having an external surface, an internal cavity for receiving cooling air, and cooling passages extending therebetween. The location and angle of cooling passages are determined using a robotic arm and a location system. A masking device is placed in the cooling passages located during the locating step. The masking device includes a head portion having a gripping feature for gripping by a robotic arm, and a locating feature for orientation of the masking device by the robotic arm. A retaining portion extending from the head portion is arranged and disposed to retain the masking device in a cooling passage. The retaining portion is narrower proximate a distal end than proximate the head portion. The component and head portion of the masking devices are coated. The masking devices may be removed using the robotic arm and locating system.
