BT-Spannschloss®

The BT-Spannschloss® (turnbuckle) is part of an easy to use connection system – without additional materials and tools.

By using BT-Spannschloss® (turnbuckle) and corresponding connection materials, precast elements can be joined together without using mineral grouting. This means no curing or standstill times due to low temperatures. The BT-Spannschloss® (turnbuckle) can be fully loaded
straight away. You can view the application of BT-Spannschloss® in our product video.
