I am a custom fabricator NOT A MIDDLE MAN, This was a special listing for a customer requesting these exact specifications to transition up to 3 5/8” Crown Molding and They can be modified if need be? These inside corner block style transitions are approximately 6 3/4" from top to bottom! Dimensions of the transition piece (top) are surface height of 3 1/2" and a surface depth 2 1/2". Purchase price is for 10 inside corners, they are much different than the standard home depot block (for $11) in that i've used a colonial very detailed moulding in the tear drop for added detail. The molding used cannot be purchased supply houses! These are one of a kind! Refer to listing photo for the exquisite detail! these have also been primed and painted two coats with Benjamin Moore super white semi-gloss paint! This lot is a custom fabrication and cannot be purchased anywhere else! It is a steal! If you need more or less, please message me with quantity needed and I will create a listing for you. If you need a different size please let me know and I will fabricate it for you! I also have many many other different sizes and styles which aren’t in my listings, again, please Message me with needs!
