Accomodates most 20" box fans. Constructed from heavy duty 1" wide nylon and plastic quick release buckles for easy on and off. Includes separate tilt strap that gives the capability to angle the fan.
"Good buy! Good price! I needed something user-friendly and inexpensive to test a few box fans in our barn and these seem to be well constructed, heavy duty nylon, hold inexpensive 20"" Walmart box fans, and are easy to hang/assemble. I've not been using them very long -- but they are much better than old-fashioned bungee cord methods! Good find!"
