    Excellent product. It is slightly larger than the post sleeve. This allows proper drainage and gives a finished look.

    Does not fit over cedar posts only

    Posted by Tammy McElroy on Aug 27 2015

    This should really say made to fit over aluminum post sleeve covering a 4x4 post, NOT "One piece unit, made to slip over 4x4 post". We were going natural and using 4x4 cedar posts around our deck so purchased these to match the black solar caps at the the top of the cedar posts. But when these arrived they are cut to fit on sleeve that is put over post so it was a good 3/4 of an inch gap on all sides. Which looked funny since it didn't fit flush with the post. Deckorators charge a 25% restocking fee. Which I think we shouldn't have to pay as it seems to have not been explained properly,nor are the dimensions of this base trim listed.
