Car Top Carrier Extra Straps Set

Set of 2 Straps For Rack

Installation Options
Back to Products page


Set of 2 Straps for Rack, for cars with roof rack (side rails, cross bars or both). Straps are heavy-duty, 1.5 inches wide, seat-belt style. They are soft, flexible and easy to work with, and have been specially treated to be water-repellent while retaining their softness.

Each strap consists of 3 sections: Rack Short Strap, Top Strap and Rack Long Strap. Sections are joined by 2 heavy-duty side-release buckles.

Total length of Rack Short Strap + Top Strap + Rack Long Strap: 98 inches.

Finger loops at the ends make it easy to tighten the straps.

Straps are water-repellent -- they don't get wet.


You can fasten RoofBag car top carriers securely to either side rails or cross bars, even if cross bars are closer than the length of the carrier (see illustrations above).

Two Straps for Rack are included with each RoofBag car top carrier sold for cars with rack.

Four side-release buckles (2 per strap) provide easy access to the contents of the roof carrier.

Buy an extra set of 2 Straps for Rack for additional installation options of your roof carrier:

Fasten your car top carrier to both the crossbars and the side rails of the roof rack, for maximum attachment strength. One pair of straps runs front-to-back and secures the carrier to the crossbars, and the other pair runs side-to-side and secures the roof carrier to the side rails.

If your car has only cross bars, you can fasten the rooftop carrier to the cross bars using 4 parallel straps running front-to-back for greater attachment strength, a quieter ride and better fuel savings. (Loose fabric, especially in a less-than full carrier, tend to cause noise, lower fuel efficiency and possibly cause fabric damage).

If your car has only side rails, fasten the rooftop car top carrier to the side rails using 4 parallel straps running side-to-side for greater attachment strength, a quieter ride and better fuel savings. (Loose fabric, especially in a less-than full carrier, tend to cause noise, lower fuel efficiency and possibly cause fabric damage).


The Top Strap slides under the strap guides at the top of the carrier.

The Rack Short Strap and the Rack Long Strap are fastened to the rack using a slip knot. Loop the buckle around the rack, thread the buckle through the strap loop at the end of the strap and fasten to the Top Strap by sliding the two halves of the side-release buckles into each other. Click for installation details.

The length of the each strap is adjustable at each of the two buckles. To adjust, pull from the Finger Loops located at each end of each strap.

Secure the free ends of the straps by wrapping the free end around the taut section of the strap and tucking the end under the last turn. This avoids flapping of the free end during travel (see diagram above).

If a strap makes a whistling or a rumbling noise during travel, unbuckle the suspect taut section of strap, twist it half a turn or one full turn and re-buckle.
