This was the only brand I could find online in that size. I received the pack of 2 terminal cups from Mo-gu within 2 days. I was impressed that they came with a rubber gasket and they were not as flimsy as others have said. They terminal screws tightened down on the speaker wire tightly and the screw holes lined up with the existing holes perfectly. It came with 4 black wood screws but I reused the old screws since they were slightly thicker. ## Features - Terminal cup for speaker subwoofer boxes.
