A fastening system includes a ratchet head and a strap having a pair of side edges, a first side defining a base surface, and a second side having a plurality of teeth. A pair of troughs extend in a longitudinal direction and each is positioned interstitially between the plurality of teeth and a side edge. A plurality of standoffs are provided on the second side of the strap along each of the side edges, the standoffs extending from the base surface at least as far as a distal extent of the plurality of teeth. The ratchet head has a ratchet pawl operable to engage the plurality of teeth to adjustably receive and secure the strap.
