Customer Questions & Answers

Is the outside of this safety seal flat?

I want to hook this with command strips to the underside of the porch roof, it's completely dry and a good spot to hold something securely out of the way, I just need it to have a flat surface to attach. Thank you.
Asked by: Cat

will the Twist and Seal Model # TS-1000-G-BL accommodate the junction between two outdoor extension cords of standard size?

Rated 5 out of 5 by from Great invention!!!! The cord safety seal worked great with the Christmas lights outside. It saved a lot of time not having to tape all the connections. I have ordered additional ones to give to my neighbors for next year.

Rated 4 out of 5 by from bright lights for Christmas!! Let it rain! Our Christmas lights would fault off no matter how we taped the extension cord connections. The safety seals did the trick. The entire neighborhood loves our lighted tree.

Rated 5 out of 5 by from The connector Tested after a lot of rain and no shorts so far. It is cheaply made but does the job. Not sure if it will last for 2-3 years in the lawn.

Rated 5 out of 5 by from Great Idea Always worried about exposed extension connections, this solved the problem. Fits snug & adds the protection I had hoped for.

Rated 5 out of 5 by from Fantastic for Holiday Decorating A friend of mine used these last year for holiday decorating and raved about them. I looked everywhere to find them (and couldn't). I am so thrilled to see them here. These are the best little gadgets to keep all of your holiday lights plugged together and protected from the snow/rain. No more 1/2 dark bushes because one of the cords has come unplugged. Get them now, because once everyone starts decorating in a couple of weeks they will be tough to find!

Rated 5 out of 5 by from Works as good as they say. Every Xmas time I have always had problems with the lighting outside. The rain or snow would cause all kinds of problems. Problems solved with this product. It keeps all the connections dry and I have not had a problem since using these. Great product.
