no there are no holes through it,completely solid all around.The sides have no sharpness to them,it is rounded and about an 1/8 of a inch thick The tip is about 1/4 inch wide.
Jeff,are talking about a wrought iron fence sort of ? This foundation was out in the sticks in the poor ravaged pa hills :-) I doubt houses had fences around or in front of them.
The groove around the round part makes it look like there was a leather or rubber "O" ring around it for sealing. It may be off of an old Iron steam radiator ( Pressure relief valve)
