Some assembly required and elbow grease. Almost went togerher per the instructions. Needed a mallet to drive home the pieces. I recommend also using glue. The rocker pieces were not correctly drilled or located. Hecho in China. 'Nuff said.
This is the best quality exhaust fan blade that I have found. I've replaced the fan blade twice previously from other supplies because they were poor quality. This one is made of thicker material and has held up nicely since I installed it.
