Part works as it should

by Susan A. -

I purchased this replacement track because I had not installed the original parts correctly and the track was stripped somewhat by the motor gear after a few months. After making sure all the parts were exactly lined up (I had to add a spacer behind the track), and the door slid easily (I had to trim off some pile insulation), everything works great and we are super happy with our automatic door. Grandma in a power wheelchair can now easily open and close the sliding door with a remote control.
