Question:
Hi - I have an Adarac Aluminum Pro truck rack and Im looking to purchase the Thule Pulse 615 cargo rack. The Adarac crossbar is 1 1/2 square and It looks like this Thule cargo box TH615 uses the older Thule FastGrip clamps TH94JV which would fit my Adarac crossbar that is 1 1/2 tall. Can you verify this is correct? Ive looked at the newer Thule boxes but they use the newer Thule clamps dont seem to fit the taller crossbar on the Adarac I have. Thanks, Matt

Good question Matt, you've definitely done your homework!
Yes, your understanding is correct. The Replacement Fast Grip Clamp # TH94JV is the same mounting clamp used on the Thule Pulse Large cargo box # TH615. The FastGrip clamps are designed to fit crossbars up to 3-5/16" wide and 1-11/16" tall, so your Adarac Aluminum Pro's 1-1/2" square crossbars are well within the clamp's capacity.
You're also correct that many of Thule's newer cargo boxes use the PowerClick mounting system, which has different crossbar limitations. The older FastGrip design is a better match for your taller Adarac crossbars.
May I ask what truck you have the Adarac Aluminum Pro mounted on?
