A mobility restriction device that is less likely to cause concerns about individual defeats, making it easier to aggregate the number of installations.
The "BB Stopper" can be used as a movement restriction device with high reaction force and large elongation capacity. In PC girders, large anchor bars and caps can interfere with the upper structure's reinforcement, but this product has minimal interference. Additionally, it is easy to consolidate the number of installations, reducing concerns about individual impacts. 【Features】 ■ Can be used as a movement restriction device with high reaction force and large elongation capacity ■ No cross-section loss occurs when the upper structure is a PC girder ■ Minimal interference ■ Easy to consolidate the number of installations ■ Reduced concerns about individual impacts *For more details, please refer to the PDF materials or feel free to contact us.
