TRADE NOTES AND NOVELTIES AND MECHANICAL DEPARTMENT. · · THE NEW "DUGGAN" CLEAT
The accompanying cut represents the new porcelain cleat which C. S. Knowles, of Boston, is introducing to the electrical trade. As will be seen it is in two halves, both of which are interchangeable, being exactly alike, and either half of which can be used at will as the bottom or the top. The advantage is apparent, as, so long as there is more than one piece left in the barrel there is a complete cleat, avoiding all the annoyance of matching up two separate parts, which has been a great source of trouble in the past.
The cleat is well made of the best porcelain, is a thoroughly durable article, and will save wiremen a large amount of time and trouble. |
