Mini - mounting width: 1.5" - mounting height: 4" - total height: 5 1/4" Our crown moulding inside-corner blocks are designed to smoothly join and complement our do-it-yourself crown moulding strips. These stylish blocks can also be used to create crown moulding outside-corner blocks perfect for transitioning your moulding around corners for a seamless, professional look. Combine two crown moulding inside-corner blocks to create a centre corner block that adds an amazing finishing touch to your beautiful new ceiling. Corner blocks are easily painted with any water-based paint and glued together with painter’s caulk. They are available in five sizes ranging from mini to giant, so there is sure to be one to fit any of our do-it-yourself crown mouldings. Crown moulding corner blocks are a great way to connect your mouldings in inside corners, outside corners, and anywhere in between.
