I have a customer who is looking for 1000-1500 Nielson Moulding Wing Hangers. They are shaped like a tappan corner, but with a notch that slides into the channel, with holes at the end of the wings for wiring. We sold him that quantity 30 years ago, and now he wants more! (?) I haven't been able to locate them at United, AMS, or other suppliers, and I suspect they are no longer made. Anyone have any ideas?
