Without a doubt, using a winding tool like Surewinder makes the most ergonomic sense for saving shoulders and wrists over the course of a career.

— Dr. Anthony Harris, Door and Access Systems Manufacturer's Association

This tool is amazing. The Surewinder, or Shoulder Saver is a career saver. I was down to installing a few doors a week. Now I am back to business and installing a few doors a day.

— Saahir Ali, Professional Choice Garage Doors

I have been running the tool through the grinder and man it works great! I would recommend it to anyone, & being an older veteran door man, my shoulders feel better than ever!

I want to give a shout out to the Surewinder. This one is easily 5 years old and works like a charm.  This is how you make one of the most dangerous tasks safe and easy.

All I can say is I should have had this tool 15 years ago–no more sore shoulders and elbows, money well spent!

Our company has been using these tools for 5 years and have had no troubles. Great tool.
