Metal drive pockets

Metal

— metal housings are most often made of steel, but there are also other options (for example, aluminium alloys).

Only this option is found in internal drive cases (see “Type”) – this is due to a number of features of such accessories. As for external models in a similar design, they are much stronger and more reliable than plastic ones, and the metal housing creates an additional feeling of solidity. The opposite disadvantage of these advantages is a higher price.
