A pair of very high quality, black-booted, gold-plated, croc clips designed for the new 2mm ESR plugs. The sockets are superb quality, gold plated and compatible with industry standard 2mm banana plugs. These fit easily and securely to the 2mm ESR plugs. Please ensure your lead has the gold plated 2mm (male) plugs on the end. If your ESR unit does not already have 2mm plugs on then you need to order the ESR full lead set(which includes the crocs too).
