Cam buckle straps with heavyweight nylon webbing are just the ticket for securing luggage on your roof rack. Each summer we take a bicycling trip with a group of friends and usually our luggage carrier is overloaded. We have tried getting the group to pack less but that has had minimal success. It has been easier to pile the extra luggage on the roof and secure it with cam buckle straps.
We sell these straps with several choices of webbing colors. They are all made to order so we can set them up to meet your needs. Just give us a call at (253) 883-5800 and we will work with you to get them just right.
If you need something stronger we have ratchet buckles although they are not as easy to adjust.
I am in favor of using more straps rather than one or two super strong models. The last thing I want to do is damage the roof rack.
