Short video illustrating how Halfen cast-in channel is installed. The video shows how Halfen channel is installed - nailed to the formwork. It also shows how channel appears when the formwork is struck. You are then shown how t-bolts are inserted, turned 90 degrees and then fixed to. This example shows the flexibility of channel fixings, and the adjustability available along the channel length. Once the final position is decided the bolts are tightened to the required torque.
