The Wire Loop Box will need to fixed to the formwork and the flexible folded wires will need to be pulled out to make a connection when ready on site. The load will be transferred from one concrete panel to the other panel via wire rope loop. High strength Galvanized Steel Wire Rope will need to be crimped by using compression sleeves / Ferrule to form a loop at one end & to transfer a load axially through other end. The load is transferred from one concrete panel to the other panel via wire rope loop.


SHINE Wire loop Box Magnet is used in Wire Loop BoxIt easily gets fixed in the magnet formwork system or on the steel table due to its magnetic properties.Our products are durable and they last for years under all conditions. With our unique combination of rubber and integrated magnets, you can make almost any shape. Once it´s in place, it stays put. No slipping, no sliding.
