These block style transitions are approximately 5 3/4" from top to bottom, dimensions of the transition piece (top) are surface transition height 2 1/2" and surface transition depth 2". Purchase price is for 6 transitions which include 5 inside corners and 1 outside corner as depicted in listing photo! These have also been primed and painted two coats with Benjamin Moore super white semi-gloss paint! This low priced set is fabricated from standard 2 5/8" crown moulding. Each additional outside corner block is $15.50 plus free shipping. I also have middle transitions which bridge 2 pieces of crown in lieu of an ugly scarf joint! Message me for additional transitions or to create a more personal listing to meet your needs! I am a custom fabricator and can usually transition anything.
