5/8" x 2" x 6" Poplar (paint grade) outside corner base block, also known as bull nose radius corner blocks. These blocks create a decorative detail that allows a clean, flowing line around a rounded corner. It prevents the need of an outside miter cut or the need for a double mitered cut (which both leave unsightly gaps). They fit with baseboards up to 9/16" thick by 5 3/4" tall, and can be cut shorter for a shorter baseboard. Unfinished; ready to be painted or stained. Made in the USA by Bonneville Manufacturing.
