DecKorators 4 x 4 Post Base Trim

These do not fit standard 4x4 posts. They are about 1/2" bigger.

About 3/8" too large for my standard cedar 4x4.Used them anyway, but seriously, they can't get them the right size? Perhaps it's a Canada/US nominal lumber size issue?

Too bad they have erroneously pasted a "post cap" description. The actual post base, pictured here, is a ring of trim that goes around the bottom of your post. Home Depot carries these too. It comes assembled with staples except for one side, and you can install it with construction adhesive.
