### ⭐⭐⭐⭐ FS-8400 Door Closer with Hold Open Feature...Installation Instructions Need Improving
*by M***R on May 24, 2021*

Installed in detached workshop with a right hand reverse entry side-door. FS-8400 Door Closer and associated parts seem heavy duty, but not sure if the hold open feature (adjust the 1 1/2" nut) will live up to my expectations over time. Overall rating would have been 5 stars, but the provided installation instructions definitely have room for improvement...better step-by-step instructions and online video(s) would be helpful!
