If you tape by hand or use machines, you can apply tape quicker when you don't have to be so precise in your 3 Way. Our innovative design has an adjustable flap to allow for accurate angle variation. Piecework journeymen will immediately recognize how quick and easy they are to install and work with. After many years in the drywall business, we have perfected the 3 Way and have cornered the market. Our unique method of corner finishing gets praise from contractors and industry experts alike. Install the 3WAY before taping. Wet the back, adjust and fit into the corner to cover any drywall or framing problems. Tapes need to go just over the beveled edge of the 3WAY or tape first and run them short of the corner. To finish just feather the edges. 3WAY Drywall Corner Finishing is more durable than paper tapes, no corner cracks, fast, easy, and perfect corners!
