These heavy duty stainless steel Speed Rails are built to endure. They come in 22, 32, and 42 inches. The rear tray is one  inch taller than the front for presentation and ease of use. Speed rails increase the efficiency of bartending by keeping the common liquors on hand at all times. It all depends on the mounting surface, but in general if you’re trying to hang the speed rail from an ice well or any piece of underbar equipment, a mounting kit will be necessary. if you’re comfortable drilling directly into whatever substrate you’re mounting against, you can skip the mounting kit.
