What is the key difference in a Rhino Drain?
Rhino drains are not injection molded! Injection molding is typically used to mass produce products for the retail market. Other than mass production, injection molded products are typically designed to use minimal quantities of raw material to produce products in shape and form at the minimum amount of cost.
