These revolutionary new holds are probably the biggest advancement in climbing wall technology in the past DECADE!  Finally, it's time to take advantage of all those unused, 90º inside and outside corners on your wooden climbing wall.  Now you can build outside arête boulder problems, inside corner routes and have killer holds to go for at the top of the wall instead of grabbing the rough edge of the plywood and framing member.  Corner Holds easily attach to the wall via high-quality, self-drilling decking screws and are a great way to add diversity and realism to any wall.
