Buying Guide
What to consider when choosing load stops
- Rack compatibility: Confirm crossbar type (square, aero, or round) and slot dimension before selecting stops.
- Material durability: Stainless steel resists rust in harsh weather; aluminum options may be lighter but less durable.
- Load width and height: Choose adjustable stops for varying cargo widths to prevent movement.
- Installation ease: Consider whether you need quick repositioning or a fixed mid-rack setup.
- Security features: Look for integrated tie-down points or additional straps to secure bulky items.
How to measure for compatibility
- Measure slot width and bar diameter on your roof rack.
- Check the product’s stated compatibility with your model or brand.
- Assess whether you need four stops or just a pair for your typical loads.
Installation tips
- Clean the cross bar slots before installing stops to ensure a snug fit.
- Place heavier items toward the center or front to balance weight distribution.
- Test the securing system with a light tug before a road trip to confirm stability.
Maintenance and care
- Wipe down stainless steel with a mild cleaner to prevent corrosion buildup.
- Inspect stops for wear or bent components after long trips or heavy use.
- Re-torque any bolts per manufacturer guidance if applicable.
Common questions
