Shubb Shubb Shubb is a company that specialises in producing capos for all kinds of stringed instruments. The company was formed in 1974 by banjoists Rick Shubb and Dave Coontz. Shubb capos remain a top-selling capo forty years after their invention. Shubb wanted to create a capo that would not make his instrument go out of tune, which has resulted in ongoing efforts to refine his invention. The Shubb Capo utilises an "over-centre" locking action, which is lever operated. The design includes a screw for adjusting the clamp's tightness, and has been described as "a turning point in modern capo design."
Metal Construction Association Metal Construction Association The Metal Construction Association (MCA) was formed in 1984 with a focus on growing the use of metal in construction through marketing, education, and selective action on public policies that affect metal’s use in building projects. The concept of the MCA began in March 1983 when members of the now-defunct Metal Building Component Manufacturers Association wanted to create a new, expanded association. MCA took shape later that year when these companies contributed seed money for the new organization: American Building Components; Binkley Company; Corrugated Metal; Engineered Components; McElroy Metal; Metal Building Components Inc.; Moncrief Lenoir; and Omega
