Standard Grain


Standard grain

This classic, geometric grain is almost literally a convertible topping “standard”. It is composed of tiny, four-sided, flat-topped pyramids. Also widely known as Pinpoint and Diamond, this grain came into widespread use for convertible topping by North American car makers when vinyl fabrics “took over” the market in the mid-1950s. With few exceptions, car makers used this for top material right up to the “last convertible” in April 1976. In the ragtop revival of the early 1980s, Standard grain was the grain of choice until supplanted by Sailcloth grain in the mid-1990s.
