Need clips to install Christmas lights on a flat roof?

Combo C clips are tailored for installation on a flat roof. Install them semi-permanently with small nails or screws (not provided) or if necessary they can be installed with silicone.

These clips are manufactured with a UV resistant rigid plastic. As you can see from the photo, one side is smaller for C7 bulbs and the larger side is tailored for the larger C9 bulbs. These clips work with only with traditional 2-piece C7 or C9 Christmas light cord and bulbs light strings. They will not work with plug-and-play mini lights or LED Christmas light sets. The clips actually snug down around the base of the installed bulb to hold them in place and non-standard strings are not compatible.

This item is for 500\ of the Combo C clips. If you think you'll need more clips for your installation or want to keep replacements on hand, consider our 500 or 2000 clip case.

Not for permanent installation, our clips are warranted for 90 days of seasonal use.

These work great on a vertical wood surface

I needed a way to hang C9 bulbs on a balcony but I didn't want to damage the wood. Since 2020 I've been using these clips with Command strips and it's worked well. Some of the bulbs have to be unscrewed a bit to fit them in (then retightened) but I think that's due to the way the bulbs fit in the sockets. I haven't had any problem with the clips not keeping the string in place, even with wind and rain. In January, I simply pull the strips out and you can't tell that they were there.

C7 slots too tight

these are pretty tight for the 7's. Also, if they get direct sun thru the summer months they shrink a smidge - you'll have a difficult time getting 9's or 7s in them

HW39006-50 Combo C Clips

The Combo C Clips work great for just about any install. They are durable and hold with the C9 or C7 bulbs. I actually use both the Combo C Clip and the L Clip.


The combo clips just simply work great for me to install and put up my Christmas C9 lights. love, love love them
