Pyramid caps
Pyramid caps are fence post caps that are shaped like a shallow pyramid, and are used on square posts.
One type of fence that often uses pyramid caps is vinyl fence, which uses pyramid caps that are slightly larger than the outside dimensions of the fence post, so that the cap fits snugly around the post. You can use an adhesive or even silicone to ensure that your pyramid cap stays in place on your fence post.
Check pyramid caps from time to time, and replace any that are cracked or damaged. Not only will they ruin the appearance of your fence, but they will let water get into your fence, which can cause corrosion problems or, in places that freeze in the winter, lead to cracked and damaged fence posts.
