Many people who purchased this silicone rubber roller for glue have complained about the roller binding up. This is because it is catching on the bend and jamming up. One person posted on amazon that a washer helps. I came up with this 2 piece spacer that holds everything where it needs to be. Place roll2 on and superglue roll1 to hold in place.
