Thule Load Straps with Steel Cam-Action Buckle and Protective Bumper, Sold in Pairs Review (2026)

What makes the buckle different

The defining feature of these straps is the steel cam-action buckle paired with a protective rubber Buckle Bumper that fits over it. On many generic cam straps, the metal buckle can swing loose during driving and tap against a vehicle's roof, hood, or a kayak hull, leaving small dents or scratches over repeated trips. The rubber bumper is designed specifically to prevent that kind of contact damage while still allowing full access to the cam mechanism for tightening and release. A steel buckle also tends to hold tension more reliably over time than a plastic cam buckle, which can wear, crack, or lose grip after repeated tightening cycles in sun and cold.

Webbing and durability

The webbing itself is a heavy, flat, UV-resistant nylon, built to resist the kind of sun degradation that gradually weakens straps left outside or stored in a hot garage over a season. Thule sells these as a roof rack accessory brand rather than a generic hardware supplier, and the strap's construction reflects that focus, with flat webbing designed to sit securely against a kayak or gear without excessive twisting during tightening. A pair typically weighs under a pound combined, light enough that carrying a spare set in a vehicle for backup or for tying down additional gear is a reasonable and low-effort precaution.

Length and what to check before buying

Thule offers this load strap style in more than one length, including shorter and longer pair options meant for different rack widths and load sizes, and the specific length is not printed in this listing's title. Buyers should confirm the exact length in the product's size or variation details before ordering, since a strap that is too short will not reach around a wider load or a taller roof box, and one that is too long leaves excess webbing flapping at highway speed unless it is tied off. Measuring the distance needed to wrap around the kayak and both crossbars, with enough slack for the cam buckle to tighten, is the most reliable way to figure out which length variant to choose.

Using them to secure a kayak

For kayak transport, these straps typically run over the hull and around both roof rack crossbars, with the cam buckle providing quick, tool-free tightening and a reliable hold at highway speed. The rubber bumper matters most in exactly this use case, since the buckle often ends up resting close to or against the kayak's deck during the drive. Straps should always be paired with a bow and stern line tied to the vehicle's tow hooks or frame for a fully secure setup, since roof rack straps alone are not intended to be the only thing holding a kayak in place on the highway. Checking strap tension again after the first few miles of driving is good practice, since webbing can settle slightly once a load shifts into position.

Who should buy these straps

These are a solid pick for kayak, canoe, or roof box owners who already trust Thule's rack hardware and want matching-quality tie-down straps with a buckle that will not scuff paint over repeated trips. The price sits above generic no-name cam straps, which reflects the steel buckle and protective bumper rather than just the webbing itself. Buyers on a tighter budget who are comfortable with a plastic buckle and are careful about where it rests during transport may not need to pay the premium for the steel and bumper combination. Anyone unsure which length to order should measure their setup first rather than guessing, since length is not specified in this particular listing.
