Review on 🍌 Premium Deadbolt Flex Pin Banana Plugs - 6 Pairs Gold Plated Plugs for Spring Loaded Speaker Terminals by Ryan Hawkins

Spring loaded clips will fit 14 or 16 gauge wire. The 12 gauge wire is simply pulled out of the terminals because it is too thick and the springs are pushed all the way down to get the wire into the hole so there is less pressure on the wire. That's where these flexible pins come in. Thread 12 gauge wire into these flex pin connectors and push in. Although they are also thick, they are braided and allow the spring clips to better grip and hold the flex pin tabs. So that they don't pull themselves out of the spring clip. Good smart product. The only thing I noticed is that you can use black vinyl tape to insulate the flex pins from shorts. There is not much space behind my setup. The pins looked like they were touching, so I put black tape on the flex pin caps. They hold up great and my speakers sound great. If you're using a heavier gauge wire, or just want to hold the wire securely in the spring clips, use some of these flex pins.
