I have been looking for one for a while, with no luck, until the other day. I was in Home Depot and as I was looking in the area for something like a spring clip for a broom, I found it. It looked like it would hold a HUGE screwdriver, but worked great for the vertical holder I wanted. I don't have the package though. I mounted it on the wall, with just a little upward pressure on the pump, and it holds it nicely. The little lip stops any forward movement and the tension keeps the shotgun upright.
