Pat is very goo,very handy,easy to use. Only negative is the price. probably high priced because of convenience.
These little rivets are a little pricey, especially with the minimum quantity requirement. But they work very well. I found the easiest way to install them was with a pair of channel-lock pliers. Just set them to the width of the track, and squeeze the pin into the post until it's fully seated. No hammering that could damage anything (like thumbs!).
