All SUS-made emergency telephone box for tunnels 'TT-G(S)'

A new mechanism that does not use auto hinges! The debris discharge mechanism at the bottom of the rail prevents the accumulation of dirt.

The "TT-G(S)" is an emergency telephone box for tunnels made entirely of SUS, featuring high durability and long lifespan, which reduces replacement costs. It employs a new mechanism that does not use auto hinges. It achieves a sliding door of the same size as conventional models, eliminating the risk of being trapped due to door deterioration. The waste discharge groove, used in conjunction with the guide at the bottom of the door, penetrates the foundation, preventing waste from accumulating under the rail. This eliminates the hassle of cleaning the lower rail and reduces obstacles to door opening and closing. 【Features】 ■ New mechanism that does not use auto hinges ■ Sliding door of the same size as conventional models ■ Waste discharge mechanism under the rail prevents accumulation of waste ■ Easy leveling of the box even after installation ■ Made entirely of SUS for high durability and long lifespan, reducing replacement costs *For more details, please refer to the PDF document or feel free to contact us.
