electrical cord

If you actually have a 5x5 hole just put a 180* bend in the electric line and put the "U" in the hole and push. When that runs out put in another "U", etc. Mine goes in a 1 inch hole and I have a time getting it in. Sometimes I have to pull out 2-3 feet and try again.

I'll bet it's a real bear when it's cold.

There is one advantage of the "mouse-hole" -- if you want to run another 15-20 amp device, you can thread another extension cord through that hole so you can have another electric heater.

Of course, there are advantages of cutting it off and putting a male plug on it. The "mouse-hole" does attract vermin, so sealing it off is one less place critters can get in.

If you do put a male plug on it, make sure you get a marine grade connector and do it right, so it isn't a place water can enter.

Hi,

Many of us have cut off the cord and put a male plug on it. Then we go to Walmart and get a new 30 foot cord to use.

30 amp rv plug

if I'm understanding ur question, no. it's just a 5x5 box, that is very deep, with
a door u close when not in use.

Try, Wiping it down with silicon lubricant. Follow up with dry towel.
