FIT TIPS

  • If you are using the side rails or cross bars to attach the car top carrier bag to the car, measure the distance between the cross bars or the side rails. The roof top bag needs to fit inside of the bars and allow enough room to attach the straps.

  • The edge of the roof bag can hang over the bars, but will need to be strapped to the car with either car clip straps or straps that run through the car.  Loading the bag is easier when done on the roof rather than the ground in this case.

  • Straps can pass across the bag from the left to right on the vehicle or from front to back.  This allows for lots of flexibility in how the roof top carrier is attached. 2, 3 or 4 straps can be used.

    PackRight Sport 3 Car Top Carrier

  • To attach the straps to the side rails an open space of approximately 20 inches is needed. Some vehicles may not have enough of an opening to permit 2 straps across the bag from left to right. Options would be
    • Attach to cross bars
    • Attach one strap to the roof rack & the other thru the vehicle body
    • Attach one on the roof rack from left to right and 2 to the cross bars from front to back (see picture)

  • For a perfect fit measure the roof of the car and compare it to the length and width dimensions for each car top carrier.  On a vehicle with a curved roof measure the flatest part of the roof for a good fit.

  • Be sure to pass the straps across the bag to attach.  Do not only attach to the "D" rings.  The "D" rings should act as a guide for the straps not as a way to secure it to the roof.
