C-Clamp

I had to order a new clamp because the knob broke off the first one. Also, I had an issue with the knob coming off when I was trying to loosen the clamp and had to use pliers to get the clamp off of the cart. I don’t know if you can do something with a lock washer or something like that to prevent that from happening. Otherwise, I like the clamp and the fan.

Twin coolers. I replaced my homemade air conditioner.
