re: A Friend's Request

It is an interesting way to hold the shelves but while they are 7" back to front, there is 1 1/2" holding the shelf in place with tight friction.  The shelves enter the frame and extend flush with the back wall with 3/4" thickness of the upright sides and 3/4" top and bottom cross members providing the needed support.  There is only 5 1/2" extension.  Also on the original the shelves will hold  nearly 15 lbs.  And this one will only have  a collection of owl statuettes that weigh less than 6-8 oz each.
