The VSD provides excellent vestibular and proprioceptive stimulation because it allows controlled bouncing and vertical movement. It comes complete with two locking safety snaps and four industrial quality elastic loops - two single loops, each with a working load of 30 lbs., and two double loops, which have a working load of 60 lbs. per double loop. This setup provides a working load range of 30 - 180 lbs. You can add additional double loops in place of the single loops to increase your VSD's capacity to 240 lbs.PLEASE NOTE: The life span of the loops will depend upon the intensity, frequency and duration of use. While they may last a very long time, the typically demanding use of this particular product necessitates a higher rate of replacement. Therefore, SOUTHPAW CAN ONLY WARRANTY THE LOOPS FOR SIX MONTHS.Southpaw does not recommend that you use more than four double loops at a time on your VSD.
