Camlocks allow the quick and easy release of hoses or other fittings without the need to unscrew. This is especially handy when using hose. Camlocks come in male and female forms. The male part attaches to the container. The female fitting is connected over the male fitting and the metal handles are clicked back allowing the two parts to lock together.
The male and female fittings come in various thread types and with hosetails if needed. The parts are sold separately allowing you to mix and match the parts that you need.
