Deadbolt Flex Pin Banana Plugs for Spring Loaded Speaker Terminals
The new Flex Pin Deadbolt Banana Connectors give you all of the benefits of Banana Plugs for your legacy style receivers and speakers.
Standard Banana Plugs won’t work with Spring Clip Terminals. Many old receivers and speakers and some new speakers and receivers use this type of terminal shown below. Our Flex Pin Deadbolt Banana Connectors are designed to work with these spring clip terminals.
Flex-Pin Deadbolt Benefits
These are the absolute best connectors for vintage spring loaded amplifier and speaker connectors I have ever found!
Bought the Deadbolt flex pins thinking that they would be compatible with the Deadbolt banana pin cables and that I could just unscrew the ends and swap them. Wrong! Turns out the thread sizes are different. The solution was to cut the soldered ends off the cables and install the flex pins. Would make sense to me that you could just swap the tips by unthreading one for the other. Fortunately their tech support was very helpful. Overall their products seemed very well made.
Metal bodies of flex pins will short out on 8 speaker outputs. I have ordered 1.5” shrink wrap to cover them, a nuisance and a $15 additional expense. Product appears not to have been thoroughly tested.
Very pleased with the high quality of the Sewell Deadbolt Flex Pin Banana plugs. Best quality on the market. Period.
A deadbolt is a bolt engaged by turning a knob or key, rather than by spring action.
The term implies security and is a good name for these plugs as the special design does provide additional reliability of continuous connection.
The gold plating on the braided weave of the Flex Pin helps insure sound quality by lowering the insertion loss. These banana plugs adapt higher gauge wire to smaller terminals by accepting the heavy gauge wire as high-end speaker cables tout.
The large outside diameter of the flexible pin does not fit into the smallest of spring clip terminals found on some vintage audio gear. The pin is too long for most applications.
Although the plugs will not short together, the braided wire can. I added short pieces of heat shrink tubing over the base end of the braid to prevent this. This aside, they are fast and easy to install onto your favorite speaker wire cable. In spite of these two weaknesses, I have found these to be the best solution available and the only current product I would give a four star rating. If these plugs had shorter pins with just a slightly smaller outside diameter, I would give them five stars. For use in regular banana jacks, I prefer banana plugs with the locking expanding tip design.
