It is compatible with plastic chains made of 4 mm beads strung on polyester cord. Standard endless plastic chains are 300 cm long, and with this lock mechanism, you can join and adjust the chain to your desired length.

This accessory is both durable and stylish, making it a practical solution for curtain systems.
