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
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.
