Roller support restrains one translation degree of freedom in two dimensions. It provides themes, plugins and add-ons for the roller blog server. A roller support attachment is mounted on the cross piece of a conventional sawhorse through the use of a pair of bolts. It is available in different types such as super-duty and standard duty roller support. It is designed to capture round or unusually shaped items, which require infeed or outfeed support. It is free to rotate and translate along the surface upon which the roller rests. Roller supports are always found at one end of long bridges so the forces due to thermal expansion and contraction are minimalized.
