Check the listing for details. Crown Molding Corner Inside Blocks (12 pack) Blems For 3 5/8" Crown!. Condition: New. Listed at 59.99 USD. These block style transitions are approximately 6 3/4" from top to bottom, dimensions of the transition piece (top) have a surface height of 3 1/4” and a surface depth of 2 5/8". purchase price is for 12 inside corner blocks. These are blems which didn't pass my standards but are still well made and sound and will transition up to 3 5/8" molding perfectly! Be weary of a seller who's transition specifications are smaller than these. Crown molding should have a nice reveal when transitioned. At only $5 each these are a steal as reflected in my positive feedback. This is a lowball price for someone looking for a bargain! These have also been primed and painted two coats with Benjamin Moore Super White Semi-Gloss Paint. i am a fabricator (NOT A MIDDLE MAN). all my transitions are fabricated in my shop. I also have middle transitions and outside transitions that can be combined with your purchase. Simply message me with needs.
