  1. Undersized Review by MT

    The material is OK but the insert was undersized, not 7/8 inch as advertised. 7/8 inch = .875 inches, the insert measured .820 inches Do not recommend them (Posted on 7/10/2018)

  10. Too Loose Review by MattM

    These were just a little too loose for our application - they fit, but fall out too easily. I could have glued them, or wrapped them with electrical tape before insertion, but glad I didn't have to. Fortunately I bought SKU: 30-604 at the same time. They fit well, and will stay until I need to replace them - I'll be buying more of those today. (Posted on 4/17/2016)
