Heavy Duty Binding Post Red/Black Pair for 1/4" Ring Terminals (M6)

I like that they screw completely off and allow for ring terminal connectors to be used, unlike the many cheap ones you will find on Amazon.  They are nice and sturdy and well worth the price.

I use these binding posts in a 13.8 volt DC, 45 ampere linear power supply that I designed and built for use with a 100 watt Amateur Radio transceiver (45 amps is overkill I know, but I designed it with future added loads in mind).

Although the connection to the radio itself is accomplished using the neat-o Powerwerx PanelPole round housing and PowerPole connectors to connect the radio's power cable to the supply, I also wanted a set of binding posts in case I needed to "borrow" the power supply for something else (charge the car battery, etc.).

The binding posts are very heavy duty and nicely made. The posts fit both M6 metric and 1/4 inch ring terminals. The metal parts have a nice shiny finish (nickel plated). The package comes with all the necessary mounting hardware (flat washers, split-lock washers, nuts and anti-rotation insulator bodies).

The insulator bodies have a "shoulder" to center the assembly in the chassis hole, insuring that installing the post off center is impossible, as well as providing insulation between the post and the chassis. The required hole size in the chassis is 12.7mm (1/2 inch).

The insulator bodies are very heavy duty material (polycarbonate I think). They also have anti-rotation pins molded into them to prevent rotation (which would require matching index holes in the chassis. These index pins are easily removed with a razor blade or hobby knife if they are not needed. The insulator bodies also have a molded hex indentation which mates with the outside end of the metal post to prevent rotation or loosening during use. And, of course, they are color coded red and black.

Cleverly, these binding posts are designed to accept not only ring terminals, but also banana style connections (wire through the post, wire wrapped around the post and banana plugs).

Unlink most "5-way" binding posts, the thumbnuts on these binding posts can be completely unscrewed and removed, allowing a full round ring terminal to be connected, washers added, etc.

In summary, these binding posts are nice looking, very heavy duty and have many little, but very useful and clever features. The engineer who designed these had his (or her) thinking cap on!

I highly recommend these binding posts for any project that needs... binding posts :)

Both thumbs up!
