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 method of forming a cooling assembly in a turbomachine part is provided. The method includes placing an encapsulated diffuser insert partially into a hole in the turbomachine part. The encapsulated diffuser insert has an unobstructed central passageway with a generally circular cross-section at a first end and an elongated rectangular cross-section at a second end opposing the first end. The second end has a sacrificial cap. A coating step coats the turbomachine part to at least partially encapsulate the encapsulated diffuser insert in a coating. A removing step removes the sacrificial cap to enable air flow through the central passageway. The encapsulated diffuser insert remains in the hole of the turbomachine part and the coating, thereby providing the unobstructed central passageway with a generally circular first end and an elongated rectangular second end adjacent to an outer surface of the turbomachine part.

A masking plug assembly includes a lower anvil and an elongate member coupled to a central portion of the lower anvil, where the elongate member includes at least one coupling part. The assembly also includes an upper anvil having a central opening for receiving the elongate member therethrough, where the upper anvil includes at least one complementary coupling part configured to be releasably coupled with the at least one coupling part of the elongate member. The assembly also includes a deformable plug with a central opening for receiving the elongate member therethrough, where the deformable plug is configured to be positioned within the hole of the structure between the lower anvil and the upper anvil, and where the deformable plug is composed of a resilient material such that at least a portion of the deformable plug expands horizontally when compressed vertically between the lower anvil and the upper anvil.
