This is a unique set which ive fabricated for a customer who wanted to match cove molding, Price is for a set of 4 block style transitions. The blocks are fabricated to use for up to 3 1/4" crown molding , top portion of each block is 3" in surface height  and its surface depth is 2 1/4". its total height is 4 3/4". If these heights are insufficient the height of the block can be fabricated to any specifications you'd like. these have also been primed and painted TWO COATS with Benjamin Moore super white semi-gloss paint. I also have middle transitions available. simply message me with needs.
