Aluminum patio door rollers

Hello,

I need help ID'ing these rollers. I just tuned some aluminum doors probably from the 1970's yesterday. These were the rollers. I neglected to measure the width of the assembly and height. The features that seem to stand out are the locking tabs on the front and back of the carriage. I didn't see an exact match on the website. I believe that the doors are 1" thickness and solid aluminum. The carriages were steel and the wheels are metal with ball bearings, but I'm not sure of the metal type.

Thanks

Thanks Dave,

I did notice that roller seemed to be the closest in look. I will get better measurements at some point. I was able to lube and adjust the rollers so that they are relatively smooth, but one wheel is wearing uneven and tilting sideways causing it to lean sideways. One of the rivets that hold the wheel into the adjustment slot had worn a spot in the slot so I was able to adjust the door higher and get the rivet out of the worn spot. Thanks again for your reply!
