Frequently Asked Questions

Expand all

1Will the Thule Stacker fit my vehicle?

Stackers are pretty universal — this one clamps onto round, square, and most factory crossbars. Just double-check your setup with our compatibility checker before pulling the trigger. For context on how stackers compare, see our kayak rack types guide.

2Can one person load a kayak with the Thule Stacker?

Honestly, stackers can be tricky solo because you're sliding the kayak on its side vertically. It helps to lean the boat against the car first, then guide it up. For a much easier solo experience, check out our lift-assist rack guide.

3How much weight can the Thule Stacker hold?

Individual boat weight is typically limited to around 75 lbs, but the real question is total crossbar capacity since you're stacking multiple boats. Add up all your kayak weights and compare against your bar's rating. More on multi-boat setups in our multi-kayak guide.

4Can I carry multiple kayaks with the Thule Stacker?

That's exactly what stackers are built for. You can carry up to four kayaks on their sides, stacked vertically. It's the most space-efficient way to haul multiple boats on a roof rack. I cover the best options in our multi-kayak guide.

5How do I strap a kayak to the Thule Stacker?

Place the kayak on its side against the stacker post, then secure with cam straps around the hull. With multiple boats, strap each one individually — don't try to wrap them all at once. Bow and stern lines are essential. More tips in our kayak rack types guide.

6Will the Thule Stacker work with my canoe too?

Stackers are really designed for kayak profiles — canoes are generally too wide and heavy to stack on their sides safely. I'd steer you toward a dedicated canoe carrier instead. Check out our hitch canoe rack guide for purpose-built canoe solutions.

7Is the Thule Stacker safe at highway speeds?

When properly strapped, yes — but I'd be doing you a disservice if I didn't mention that stacked kayaks catch more wind than other setups. Secure each boat individually, add bow and stern lines, and expect a bit more noise. Detailed guidance in our kayak rack types guide.
