Effortless Repair Solution for Blinds & Shades: These 30-piece transparent pull chain connectors offer a quick, cost-effective fix for broken 4mm bead chains on roller shades, Roman blinds, or vertical blinds. Measuring 0.67" x 0.28" (17x7 mm), the sturdy plastic connectors seamlessly blend with existing chains and accommodate beads up to 4mm in diameter. Suitable for restoring smooth operation to blinds, fixing drooping chains, or crafting DIY pull chains for lamps and decor, each pack includes 30 reusable connectors to handle multiple repairs. Designed to be discreet and durable, they reduce waste by extending chain life, work universally with most 4mm chains, and save cost by eliminating full-chain replacements.
