LeadStrong Zero-Gravity Smith Attachment
The LeadStrong zero-gravity Smith attachment adds a counterbalanced vertical-trajectory Smith machine to the RF1000A rack system. Unlike a standard Smith attachment, the bar on this zero-gravity Smith attachment is counterbalanced — it is weightless and can hover freely at any position on the rails. The attachment must be installed with top and bottom connecting beams already in place on the rack. It mounts to 75 × 75 mm uprights using 25–27 mm holes.
