ProBush Sockets Collection

The TestCal ProBush Socket is a cutting-edge solution for your brass conduit bush fitting needs. Available in 20mm, 25mm and 32mm sizes.
Using a standard 10mm spanner, it has a low profile of just 14mm (that’s less than the brocket), enabling access in the smallest of areas. This ProBush socket is designed to fit most UK brass conduit bush fittings easily.
