The oscillating mounting type AB-HD is the "Heavy Duty" version in the AB mount family of the ROSTA screen suspensions. For example, the AB-HD type 50-2 offers 40 % more load capacity compared to the standard version AB 50-2 (14′000 instead of 10′000 N) by a slightly higher natural frequency (f = approx. 2,7 Hz instead of 2,3 Hz).
