Ok, so I've had many requests for colossal plinth blocks which can transition almost 7" crown molding! These are approximately 11 1/2" from top to bottom, dimensions of the transition piece (top) are height 5 1/2 " depth 4 1/4". purchase price is for 8 BLOCKS. These have fabricated to use with moulding up to 6 3/4", they are much different than the standard home depot block (for ) in that i've used a colonial 6 1/4" moulding in the tear drop for added detail. these have also been primed with Zinsser 123 stain blocker and painted two coats with Benjamin Moore super white semi-gloss . the transition block bridges two pieces of crown molding in lieu of an ugly scarf joint. I also have outside corners! 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.
