I need to replace the two tandem rollers. The wheels are 1" in diameter. Which roller do I need to order? Also the screw in one of them is stripped. What size screw do I need? Can I order the screws? Thanks.

Take a look at our 81-030, 81-095 and 81-138. All of these rollers have a similar design to yours; look over the dimensions, especially the width of the assembly and its height, to see which is the right replacement. None of these rollers have a wheel diameter of 1", but you should be able to adjust the rollers to make up the difference. 

For a screw, you might be able to use our 33-071 or 33-097, but if in doubt we recommend consulting with a hardware store.
