WebThe radius can be adjusted by sliding the metal point holder across a wood beam or metal rod, and locking it by turning a knob at the desired location. Some have a fine radius adjustment. The threaded adjustment is similar to that of a Screw. The only limitation is the rigidity of the wood beam or metal rod being used. WebFeb 21, 2015 · The radius of the fillet is called the fillet radius (not always provided). Structural Beams are also known as I Beams or H Beams, and W Beams for the wider flanged versions.
