Many material options are feasible: metals, polymers, stone, wood, concrete, glass, etc. recommend locking mounting brackets as standard speeds 20m/s or accelerations 20m/s2 Standard values of maximal speed and acceleration We offer numerous e-chains® optimised for low noise.8m/s and acceleration 3m/s2.
