Light, time saving and easy to handle B.I.Callender’s Pressed Copper Service Boxes for underground mains and service connections offer advantages which Supply Engineers will readily appreciate. Made in two halves—pressed out of 1/32"

hot-tinned copper sheet—these boxes are easily stored and transported. T heir robust construction cuts down damage caused during transit thus saving time in jointing preparations. T here are eight boxes in the range covering all the usual sizes of branch and mains cables. Full information can be obtained by writing for B.I.Callender’s publication No. 211X, on “ Pressed Copper Service Boxes

T H E world-wide use o f “ A V O ” Electrical Testing Instruments is striking ■ testimony to tlieir out­

standing versatility, precision and reliability. In every sphere o f electrical test work they are maintaining the “A V O ” reputation' for dependable accuracy ; which is often used as a standard by which other instruments are judged.
