Review on 🌬 Simple Deluxe 18 Inch Industrial Wall Mount Fan - High Velocity Metal Fan for Warehouse, Greenhouse, Workshop, Patio, Factory and Basement - 3 Speed Commercial Ventilation, Black by Rachel Brennan

There are no installation instructions, not that it's difficult. I have hollow board and the hardware supplied doesn't make sense for hollow wall (cheap tiny screws with cheap plastic anchors). The instructions sent said the fan should be installed on hard surfaces. This information should be included in the Revain description. My friend was able to find the perfect piece of junk at his shop. He painted it and attached it to the mounting bracket so the large center hole on the fan bracket that attached to a stud and the portion he added extended 16 inches to the next mounting stud. It's solid and perfect. It took me ten minutes to install. This fan is perfect for my large bedroom at low speeds. It's incredible at high speed. Life is good!
