Review on 🔧 Prime-Line Products B 610 Spring Tension Roller Assembly: 1" OD, Concave Edge, Steel Ball Bearing – Convenient & Durable Option by Kevin Duhon

You can't tell from the pictures but it looks like it has bearings in it compared to my original reel with a metal shaft and hole in the middle. metal wheel. The crimped ends on the shaft feel heavier than my original rollers (which failed/worn out on my original unit). I had broken 2 casters (out of 4) and just bought one of these (yes it's a 2 pack) and now the screen door is REALLY smooth. I almost want to replace the other two OEM rollers but it's not necessary but if I do it will definitely be replaced with these blocks.
