Some use a gauge glass guard requiring a “protector slide” or “protector plate” of glass. The above list covers the sizes most frequently used. Other sizes can be made on receipt of specifications. These glass slides are specially toughened to withstand severe shocks, a quality advantage which will be greatly appreciated in glasses used on a locomotive.
