Our Spiral Gutter Clips are specifically designed to universally fit on MOST gutter types. We can't guarantee they fill fit on your gutters, but unless you've got some strange gutters, they'll fit.
If you have Gutter Guards or some other type of leaf filter on your gutters, this will cause an issue for the Spiral Gutter Clips. In that case, you'll want the Gutter Guard Clips instead, as they are designed to mount into the small holes in the Gutter Guards.
If you have surface-tension Gutter Guards (the solid type that has a little reverse-curve at the end), you'll need to go a different route entirely. In this instance, you'll need to use nails/screws/permanent hooks onto the fascia board instead of hanging things from the gutters.
