- Tall brackets
- Heavy duty construction
- Built for factory rain gutters
Gutter clamps and roof loads
Gutter clamps transfer the rack’s load to the vehicle’s roof through the factory gutter edges, so the gutter’s condition matters. Dents, bends or loose gutter attachments can reduce grip and let the rack shift. Look over each gutter section before installing the clamps, and avoid mounting over damaged or repaired areas.
Tall brackets raise the rack above the roofline, which can change clearance for antennas, cargo and a driver’s view. Space the clamps evenly and tighten them in steps so the pressure is shared across the gutter. Recheck tension after rough roads, and avoid overtightening, which can deform the gutter lip and the clamp itself.
- Check gutter edges for dents
- Keep clamps evenly spaced
- Confirm clearance for tall brackets
- Recheck tension after rough roads
