An Innovative banana plug approved worldwide as a loudspeaker cable connector due to the safety pin design. It is fully insulated using Makrolon®. A secure connection is possible through an expanding inner spike which provides high clamping power. While using only one hand, cables can be connected in tight spaces with just thumb and forefinger. Extremely compact, sloping angle is easy on cable and equipment. The WBT-0645 is stackable for bi-wiring. Two Torx™ screws for extra tight pressure connection and additional cable strain relief. Connector can accommodate a cable diameter size of 10mm² / 8 AWG.
