DEFINITION

Classification: 174/164

(under subclass 158) Devices in which the support securing or attaching means includes a portion extending into or through the support.

(1) Note. Insulators having integral stem portions for mounting in a cross-arm, wall, or similar support are in this subclass.

(2) Note. Insulator supports secured to a main support solely by nails, screws, or similar fastening elements not forming a part of the insulator support are excluded from this subclass and have been placed in this class, subclass 158, or other appropriate indented subclasses.

(3) Note. For the support penetrating features, continue the search in class 248, Supports, subclasses 71 and 216 and indented subclasses.
