I put a couple hundred of these on my house. Best clips I've found.
These are great gutter and roof light holders. Easy to work with.
I have to admit that I am . . . fussy when it comes to how my Christmas lights look and this clip is the secret to professional looking results. Works under shingles, on siding corners, raingutters or under the drip edge. Holds the light secure and in place - no dangling lights or up/down action. Not that those things are bad, it just isn't what I want. I ordered 350, going to order another 200 to make sure I have these for years to come.
These clips are perfect for a variety of lights. Easy to install, and easily removed.
