The Bench Dog Bullnose Trim Gauge is a combination layout tool and measuring aid for installing trim on rounded drywall corners. Its two wings are spaced apart exactly 5/8-inch: users can make two vertical marks for end points of standard 3/4-inch bullnosed corner trim assembly. The Trim Gauge can be mounted and used to anchor the tape measure when both corners are rounded. The Bullnose Trim Gauge has a price of $11.99.
