Inside Corner Applicators control, and divert the flow of compound onto both sides of 90° inside corners, creating two uniform ribbons of mud in a single smooth action. Smooth rolling wheels guide the head along the wall, and the stainless steel spring clip makes it a snap to attach to any length compound tube.

Our most popular model, with two smooth rolling wheels and stainless shoes, it slides along the corner and leaves an even ribbon of compound behind.
