SHEILD ROCK Slotted Double Strut Channels (82x41 mm, Back to Back) are the most comprehensive solution for projects requiring heavy loads with the need for continuous adjustment. They are manufactured by joining two 41x41 mm slotted channels back-to-back, providing a total depth of 82 mm for increased rigidity, while the longitudinal slots on both sides allow for the easy installation of accessories and nuts. This design is ideal for supporting massive piping systems and large ductwork in industrial and commercial facilities, ensuring rapid installation and maximum structural safety.
