The Lockrack SUP carrier lets you transport 2 stand-up paddle boards on your roof rack crossbars without the need for load straps. The rubber-coated arms can be adjusted to the width of your boards and ratchet into place for a secure hold. Once they are set, the arms lock into place and can only be removed with the included keys, ensuring your gear is safe and secure. Because a single person can quickly and easily load the SUPs onto the carrier, and since load straps aren't necessary, you'll spend less time loading and unloading your boards and more time out on the water.

Quick, Strapless Loading with Ratcheting Arms

Loading the SUPs onto the carrier is easy for one person to do. With the inner arms already installed, simply stack your boards on the carrier's base, making sure they're pressed against the arms. Then just insert the outer arms into the carrier and ratchet them down so they're sitting snuggly against your SUPs. Once fully locked around your SUPs, the ratcheting arms' curved design creates a lateral and downward force, ensuring your boards are secure and won't slide around. And because of this design, you don't have to use load straps to secure the boards to your roof.


To ensure your SUPs aren't damaged during transport, the ratcheting arms are covered with a rubberized sleeve. This rubber-coating flexes against the sides of your gear to protect them from scuffs and scratches, while still providing a secure hold.

For longer gear and longer trips, we recommend using bow/stern tie-down straps (sold separately). Because the carrier holds your gear in the center, the bow and stern can be subjected to damage caused by high winds. The bow/stern tie-downs provide additional support to help protect against this type of damage.


When not transporting your gear, the carrier's arms can be secured flat against your crossbars. In this position, the carrier adds less than 2" of overhead height to your roof rack crossbars. This means you won't have to remove them when pulling into your garage.

Integrated Locking System


Four locking points secure the ratcheting arms and your gear to the carrier. When you ratchet the arms down, they lock in place and can only be removed with the included keys, giving you peace of mind when you're away from your vehicle and gear. For added convenience, the keys hook onto your key ring.

Easy Installation in Top Channels


The rack installs quickly and easily into the top channels of your crossbars. Simply attach the T-bolts to the base of the rack and then slide the rack into your crossbar's channels and secure it using the included socket wrench.


If your crossbars don't have top channels, or if you prefer a clamp-on installation, you can attach the universal mounting clamps (339LRADPTR - sold separately) to the carrier instead of the T-bolts. Set the carrier on top of your crossbar's, attach the bottom portion of the clamp, and tighten the clamps down with the included tool. To access the carrier's mounting hardware, simply remove the rubber strip on top of the base.

Ask the Experts about this Lockrack Watersport Carriers

  • Best SUP Carrier For Easy and Quick Loading
    It really depends on the carrier you go for. For the Thule Taxi XT # TH810001 I recommend putting a tie down in the front. Just because there is only one narrow strap securing your paddle board to the carrier and when you're driving at high speeds the paddle board will catch quite a bit of air which will raise the front of the board. I suggest the same thing for a Yakima Rack like the SUPDawg # Y04075. Same idea here, highway speeds will raise up the front end so again I recommend using...
