Heyco offers a variety of cable management products including their M3204 cord grip. This product comes supplied with a lock nut, but inevitably the lock nut for some folks’ cord grips will decide to go out for some milk and never return. If that happens, does Heyco offer a replacement?
Heyco doesn’t, but we can help. CGLN-PG36-BK from Essentra is about as close as a replacement part is going to get, and should hopefully work for most ordinary uses of this cord grip.
