What is Attachment Type?

Some trucks are offered with rails running along the inside of the bed, which give you multiple points to attach to when securing cargo.  We refer to these rails as utility tracks.  If a Softopper is made for a bed with utility tracks, we list the Attachment Type as "Utility Tracks".  If a Softopper model is designed to attach to a bed that does not have utility tracks, we say the attachment type is "Regular Clamps" or "Standard Clamps".
