Parts ExpressAngled Locking Stacking Banana Plug with Dual Set Screws Poly Shell and Insulated Thumbscrew 2 Pair

Have used these before and really like them. The work great and lock into the banana jacks securely.

Useful but a little expensive

They work!

Second batch I bought for assembling another set of speaker cable, and highly recommend. Not much real estate in the speaker base to insert conventional bananas, let alone the locking type, but these fit perfectly because of angled inserts for cable ends.Summary: Stacking AND locking for an excellent price...what’s not to like!

Great solution for easily loosened banana plugs!

I have had mine for a good while and have had no issues. The locking mechanism works great and I have had no issues with them pulling out.

Hands down, just the best! Used every variant of Banana Plugs and These are #1 Easily. Don't look anywhere else, all the rest are JUNK!!!

These work really well to attain a secure grip. The one miss is that the knobs to tighten and loosen are hard on the hands. Otherwise, the quality and execution is great.
