A cord stop is a detail from the last part of the 19th century, intended to lock the blind cords. At that time, roller blinds were not self-rolling and spring-loaded, but were rolled by hand using the cords, much like our 18th century roller blind. Our cord stopper can be used for old-fashioned roller blinds, but can also be used for other purposes. The knob on the cord stop itself is articulated. When folded down, as in the picture, it clamps the cord in the desired position.
