BT-Spannschloss - Enables Rational and Precise Assemblies - Brochure

The BT-Spannschloss enables rational and precise assemblies as well as permanent connections of precast concrete elements. By using the BT turnbuckle and corresponding fasteners, precast elements can be joined together without a mineral grout. This eliminates curing times or downtimes due to low temperatures. The connection with the BT-Spannschloss can be fully loaded immediately. The general technical approval (Z-14.4-599) and the European Technical Assessment (ETA 19/0013) certify the reliability of the product. The BT turnbuckle is offered in three sizes – M12, M16 and M20 – and is available in galvanised or stainless steel. On 12 March 2021, BT-Spannschloss M12, M16 and M20 received the CE marking for use in the European Economic Area (EEA).
