Innovative base design allows port to be mounted on an inside or outside corner. Used to get foundation crack injection materials into a crack. Attach to concrete crack surface using surface sealer epoxy. Large base provides excellent adhesion to concrete foundation crack surface. Large diameter opening minimizes back pressure and "blowouts." Cap fits tightly and stops concrete crack injection material from flowing out of foundation crack before it cures.
Steel balls fit inside corner ports and allow the concrete repair material to flow in one direction only. Great for injecting materials overhead.
