These are so a custom fabricated hooks so a TracVan Rack can be put on a hardtop rain gutter.

The hooks never come nigh the top outer edge of the rain gutter. But instead grip from below closer to the body. This prevents bending and breaking.

Or at least more of it. Because my gutters were damaged by Yakima racks.

Still need to put a rubber material on the hooks. Haven't installed them just yet.
