I am yet to to received the item
These fit my 3-bike rack. I haven't put them on yet but they're the same as the original straps.
Exactly what I was missing
I purchased an Allen bicycle carrier for the back of my SUV. For my particular arrangment, I felt that adding two additional straps just like the bottom strap would make the attachment even more secure. I contacted Allen, and they were able to sell me two straps and shipped them to me. I am very pleased with the excellent customer service and the availability of unique parts.
Works great on my old rack!
