blocks are approximately 7 1/4” from top to bottom, dimensions of the transition piece (top) are height 4” depth 3 1/8” purchase price is for 6 Corners consisting of 5 inside corners and 1 outside corner! These have fabricated to use with moulding up to 4 5/8” they are much different than the standard home depot block (for $11) in that i've used a colonial (pine) 4 1/2" moulding in the tear drop for added detail. These pine blocks can be either stained, or primed and painted!! I also have the middle transition block which bridges two pieces of crown in lieu of an ugly scarf joint! These can also be fabricated with standard shaped moulding for any size transition instead of the colonial shape! e-mail me with quantity of each needed and I will create a listing for you and re-adjust price!
