4 inch Sheave Pulley Kit

If your 4 inch pulley sheave is rusted, bent or otherwise damaged, it is time to replace it. This isn’t a job that you need to call a professional to complete. You can do it yourself. This kit includes the sheave, strap and fastener so you can replace it yourself using just a few simple tools around your house. You want to replace this piece as soon as you see that there is damage – after all, a broken or damaged sheave can lead to serious damage over time. Pay attention to these little issues with your door and you will help prevent the big problems from occurring. Finally, remember that there are different sizes of sheaves – measure or check the size of your existing sheave to make certain you have the correct piece for the job. If you have any questions or concerns, call or contact us at DIY Garage Door Parts Online and let us help you!
