This instrument showcases four recording grade hand-bent triangles. The high carbon steel alloy has been heat treated to yield excellent sonics. The four sizes (3-inch, 4-inch, 5-inch and 6-inch) cover a full range of uses. An unusual design in these triangles is that the diameters are also graduated-starting with a thin 5/16 -inch growing up to a stout 1/2 -inch thick for the largest model. The finish is satin chrome. The included beater is a full-size (8-inch) professional model made of polished stainless steel. Mounts to a standard cymbal stand.
