Turnbuckle®

The BT-Spannschloss® turnbuckle is part of an easy to use connection system – without additional materials and tools. The BT-Spannschloss® turnbuckle enables efficient and precise assembly and durable connections for precast concrete elements. By using BTSpannschloss® turnbuckle and corresponding connection materials, precast elements can be joined 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. The building inspection approval (Z-14.4-599) certifies the reliability of the product.
