At Perma-Type we think we've manufactured some pretty interestingly shaped appliances and faceplates over the last 60 years. Perma-Type can manufacture both small and large stomal openings. Any size and most any shape opening can be ordered. Choose from our large inventory of standard round openings or have a custom opening made just for you, alone. You're limited only by your imagination. Perma-Type. An uncompromising commitment to quality. And a wealth of knowledge and expertise.
