Essentials WBT style locking 4 mill (banana) plug is probably the plug Carlsburg would build if they have a go.

Had a deep barrel and takes heavy speaker cable, which is easily clamped in place by two grub-screws.

This plug is very high quality and gold plated, with a large bore to except the heaviest cables. It is also easy to fit, having 2 small grub-screws to clamp onto the cable. The sheath is also metal and is extremely well machined, marked RED or WHITE and threaded to fit over the plug proper. It is sheathed by a full metal jacket.

Once the plug is in the socket a twisting action splays the ends and ensures both a perfect connection and one that will stay tight in place.

A set of 4 includes 2 RED and 2 WHITE.

Can also be purchased in pairs.

WORTH EVERY PENNY!
