Tautliner or curtainsider is used as a generic name for curtain sided trucks/trailers. It is the trade name of commercial vehicles built by Boalloy of Congleton, Cheshire, England. The curtains are on runners, top and bottom, and can be pulled back and forklifts used all along the sides for easy and efficient loading and unloading. When closed for travel, vertical load retaining straps are tightened between the runners, hence the 'Tautliner' name, which stop the curtain from drumming in the wind and also retain the load from slipping sideways.
The company patented the concept in 1969, and credits much of its popularity to its adoption by the haulier Eddie Stobart.
