The SRS kills felt vibration when added to your weight stack. The SRS utilizes an internal rubber dampening system with a solid center and machined aluminum caps to create a superior dampening product.
Made to fit in-line with your weight stack, the SRS flexes independantly requiring weight to be added to both ends securing the system.
Note that the SRS cannot be utilized at the very end of a weight stack and must be secured at both ends either against the stabilizer and with weights on the opposite end, or between the weight stack. Additional short threaded stud like the 3/4" stud that included in the Stud Kit (sold separately) may be required to accommodate a small amount of weight, weight cap or end protector.
