The Hillman Group's basic beaded chain spools come in #3, #6, and #10 size variants and all measure 100' long. #3 beaded chains are commonly used for dog tags and ID badges. #6 beaded chains are great for toilet repair, light/ceiling fan pulls, blinds, and key chains. #10 beaded chains are ideal for plumbing applications, blinds, key chains, and retaining applications.
