Rockler Woodworking and Hardware’s glue applicator aids in gluing setup, application and cleanup. The kit contains an 8-ounce glue bottle and threaded funnel in addition to five interchangeable threaded applicator heads. Each applicator head is customized for a specific wood gluing task — a standard glue spout, a center-line glue guide to place a centered bead of glue on board edges, a silicone brush for wider boards, a ribbed roller with angled head for even glue application on very wide boards along with a mortise tip for traditional mortises, domino mortises and biscuit slots. The applicator heads also fit Titebond 16- and 32-ounce blue bottles, the company says. Along with the Rockler glue bottle, the kit includes standard glue spout with cap, glue line centering attachment, silicone glue brush applicator, ribbed glue roller applicator, mortise glue applicator with cap, glue funnel, and cleaning brush. The kit comes in a box that acts as storage for components between uses.
