I recently purchased 21 ball bearing hinges to replace all the old exterior door hinges on my home and a rental property. I must say, these are very high quality and this is a very good company to do business with. The price was very good and included free shipping. When we were installing the new hinges, we found that one of the hinges had the wrong radius and a few didn't operate as smoothly as all the rest. I called customer service and guess what?? They answered the phone on the second ring!! The gentleman I spoke with listened to my concerns and although I was prepared to use the few hinges that were a little tight, he said he would replace the hinge with the wrong radius and he would also replace the ones that were a little sticky. I offered to send the other ones back, but he declined. 3 days later, my replacement hinges arrived at my door. What a great company to do business with. I know this should be the normal expectation, and I'm sure it is for this company, but I was very pleased with the product and with the Glideright company as a whole!! WELL DONE!! 5 out of 5 stars!!
