'''SKL rail clip'''

SKL rail clip, also called skl tension clamp. German railway is the first to develop SKL elastic rail clips. And then, they are proved to be reliable on the concrete and wooden railroad ties. SKL rail clip include many sizes, such as skl1, skl3, skl12, skl14, and etc. 

'''Nabla rail clip'''

Nabla rail clip is one of common elastic rail clips that usually work as a part of Nabla rail clip rail fastening system.
