The problem solver for space constraints! Specially designed with a low profile by integrating the socket into the ratchet wrench. 53% space savings! Slim height of 18 mm, compared to a conventional socket with ratchet at 39 mm height. All sockets can be driven with a standard 1/4" ratchet, as each socket has the 1/4" drive integrated. We also achieve the same savings with extra short bits that are integrated into the bit ratchet. Perfectly stored in a metal box with a CNC machined foam insert, compact size that fits in your pocket.
