These are custom drain plugs we supply one of our core customers on a revolving annual blanket purchase order basis. They are supplied in 3 separate pieces that are then assembled around the paneling on assembly floor. While a more expensive and more intricate option was made available to our customer initially, this pictured 3-piece option presented a simpler and drastically cheaper alternative while still fully satisfying the application requirements. Initial lead time varies depending on the size required and new tooling if applicable.
