Kanulock 4.0m Lockable Tie Down Straps – Yellow
Kanulock 4.0m / 13ft Lockable Tie-Down Straps – Yellow
The Kanulock 4.0m Lockable Tie-Down Straps in Yellow combine secure roof-rack tie downs with an integrated locking system to help protect your surfboards, stand up paddleboards, kayaks and other valuable outdoor equipment while travelling.
At 4.0 metres / 13 feet long, these Kanulock straps provide additional length for securing larger boards, multiple surfboards, SUPs and kayaks while adding significantly more security than conventional fabric tie downs.
Lock Your Gear to Your Roof Racks
Conventional tie-down straps do a good job of securing equipment while you're driving, but provide little security when you leave your vehicle.
Kanulock solves this by incorporating key-lockable buckles and stainless-steel reinforcement into the straps. Once your equipment is secured to the roof racks, lock the buckles to help prevent someone simply undoing the straps and removing your boards or kayak.
Kanulock developed the system specifically as a deterrent against opportunistic theft from roof racks, making them particularly useful when stopping at beaches, cafés, shops and campsites.
Stainless-Steel Reinforced
Each 4.0m Kanulock strap is reinforced with two 4.0mm braided stainless-steel cables running through the webbing.
This reinforcement prevents the straps from simply being cut through with a knife and also helps prevent a board or kayak being slid out from underneath the locked straps.
It's a simple but effective security upgrade over conventional roof-rack tie downs.
4.0m / 13ft Length
At 4.0m / 13ft, this version provides plenty of length for larger roof-rack loads.
Kanulock offers different lengths to accommodate loads ranging from a single small surfboard through to multiple boards and kayaks. The 4.0m version is a particularly versatile option when you regularly transport SUPs, longboards, kayaks or several surfboards at once.
The additional length also gives you more flexibility when securing wider or bulkier equipment.
Easy to Use
Despite the integrated security features, Kanulock straps work just like conventional tie-down straps.
Run the straps around your equipment and roof racks, feed them through the buckle, tension your load and then lock the buckle using the supplied key.
This gives you the simplicity of regular roof-rack straps with the added security of a lockable, stainless-steel-reinforced system.
Less Wind Noise
Another advantage of the stainless-steel reinforced construction is reduced wind noise compared with conventional tie-down straps.
Kanulock specifically highlights reduced wind noise as one of the benefits of its design — particularly useful on longer drives with boards or kayaks secured to the roof.
Yellow Colourway
The Yellow colourway provides excellent visibility, making your straps easy to identify when you're loading and unloading equipment around the beach, campsite or car park.
Combined with the generous 4.0m length, they're a practical choice for surfers and paddlers carrying larger loads or multiple pieces of equipment.

Why You'll Love Them
The Kanulock 4.0m Lockable Tie-Down Straps give you the convenience of normal roof-rack straps while adding a valuable layer of security.
The combination of key-lockable buckles and stainless-steel reinforced straps means your equipment can't simply be unstrapped or the straps quickly cut with a knife when you leave your vehicle unattended.
The 4.0m length also gives you extra versatility when carrying larger equipment. If you're transporting a SUP, kayak, longboard or multiple surfboards, the additional length makes it easier to accommodate a bigger roof-rack load.
