Protect outdoor electrical connections for a holiday display, gardening appliances or at a job site with an Extension Cord Safety Seal. The case snaps around the point where the cords come together, and a rubber seal keeps out rain, snow and mud. An internal locking safety mechanism holds cords securely together. Safety Seal is a simple solution that will prevent shorting out and eliminate the chore of reconnecting cords that have been accidentally pulled apart.

  • Protects outdoor power connections
  • Cover for power cord and extension cord
  • Keep electrical cords dry and together
  • Ideal for temporary connections like gardening, power tools, illumination and holiday decorations
  • Rubberized closures on each end make the extension cord safety seal easy to use
  • Green color will help blend into the outdoor and holiday surroundings

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.

Rated 4.6 out of 5 by 13 reviewers.
Rated 1.0 out of 5.0 by Cheaply made. does not adapt to various size cords This item is just too big and bulky, is cheaply made and does not fit a variety of cord sizes. October 22, 2015
Rated 5.0 out of 5.0 by Great cover Had plenty of room for different plug types and as water resistant as it could be. March 10, 2015
Rated 5.0 out of 5.0 by Does the job WELL!!! read online that when you hook up outside extension cord to heated bird bath it can cause a trip. looked on Home Depot website for weather proof cover for cord connection. Has been in use now for three weeks, rain and snow. NO TRIPPING!!! February 17, 2015
Rated 5.0 out of 5.0 by 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. January 13, 2015
Rated 4.0 out of 5.0 by 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. December 31, 2014
Rated 5.0 out of 5.0 by Great Idea Always worried about exposed extension connections, this solved the problem. Fits snug & adds the protection I had hoped for. August 26, 2014
Rated 5.0 out of 5.0 by 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! November 6, 2013
Rated 5.0 out of 5.0 by Does the Job This little safety seal does the job and keeps the connection dry and the GFCI from popping. June 17, 2014
