This is a custom set requested by a customer, it consists of 4 inside corners to transition 4 5/8” crown molding. I also have outside corners and middle transitions which are made to bridge 2 pieces of crown in lieu of an ugly scarf joint, Each inside corner is approximately 7 1/4" in total height and the actual transition portion dimensions of each piece are 4” in surface height and 3 1/4" in surface depth. These have been cut flush for a modern, sleek reveal as shown in listing photos! These are made from 4 5/8" molding which was purchased at Home Depot. These have been primed and painted with 2 coats of Benjamin Moore Super White Semi-Gloss Paint. This set can be modified in size and quantities if need be. we are custom fabricators and can usually transition any Size, Shape and Quantity. simply message us with needs.
