1.--1 A SPANNER which can be used on round, square. hexagonal and components of irregular shape, has been
introduced. The operative part of the spanner is a length of chain, one end of which is permanently held in the split jaws of the handle, whilst the other end takes up a temporary anchorage in the split jaws.
To use the spanner, the chain is drawn through the jaws until it closely encircles the object to be moved and the efTect of turning the spanner serves to, draw the chain tightly round whatever it surrounds.
The Gripital Mark III spanner, which has a capacity from 1 in. to 4 in., costs 17s. 6d.. and the Mark IV, which is suitable for use on objects from 2 in. to 6 in. in diameter. sells for 47s. 6d. The distributors are Industrial Chain Supply Co., Ltd., 625 Fulham Road, London, S.W.6.
