Good quality

Wires are tightened in by twisting terminal caps, it is not spring loaded. Will work fine for any application. I have found others for less money but this a quality product from a good company. Also a great add on if you need to spend a few dollars to get free shipping.

Great quality for the price

I've bought at least 5 of these over the years as I've made boxes for people. The quality is fantastic, they're strong, durable and are easy/straight forward to install. I'll definitely keep buying these for future projects.
