The WBT-0726 is an economy version of the WBT-0725 Power Bridges. This version is not insulation and is not elastomer damped. Power Bridges can be used in conjunction with any WBT binding post (except the WBT-0702 series). When purchased with WBT posts, Power Bridges make an excellent modification to any bi-wire loudspeaker. Please refer to the diagram to the left for required mounting dimensions.
