    Trying to find replacements for 23 year old fence post cap plugs wasnt easy because most places only carry 2 square size or they charge up to $7 just for 1 plug. Amazon to the rescue. Perfect fit. Now, all I have to do is paint it to match the fence color.

    I had a single open tube on my fence that needed one of these plugs. I had a hard time finding them locally so had to purchase this 12 pack. The price was right and it saved me the headache and cost of driving around looking for them. It fit well, looks just like the existing caps on other posts and was priced right. What more could you want?
