A popular neat fixing for making loops in the ends of wires. Suitable for all sorts of light duty hanging applications - shelves, lighting, artwork and so on. Very simple to fix and adjust in-situ with an allen grub screw holding the wires in place. Designed for making loops in 1.5 mm and 3 mm wires, they can also be used as stops for 3 mm and 6 mm wire respectively.
