[SPECIFICATION]
| Instructional Placard | Easy to understand exercise placards feature large set-up and start and finish position diagrams that are visibly easy to identify. QR codes provide quick and easy video instruction from your smart phone or Preva app. |
| Weight Stack | Units have fully shrouded weight stacks in full compliance with ASTM and EN standards. Each selector plate is entirely precision-machined on all surfaces. Top plate has replaceable precision self-lubricating bushings. The plates feature a black painted protective finish. Guide rods are precision centerless ground, polished, with corrosion-resistant plating for smooth operation and rust retardation. The weight stack is elevated to facilitate user pin selection from seated position. |
| Upholstery | Premium-quality 3D urethane molded-foam padding for maximum comfort. Fabric meets or exceeds California fire regulations (Bulletin 117, section E). Automotive-grade, two-textured fabric features double top stitching on all seams. |

| Water Bottle and Accessories Holder | The drink-and-accessory holder features large open, even surfaced area, easily accessible and easy to keep clean. |
| Frame and Finish | The frame is 11 gauge (.120 in) 2x4" electroweld steel racetrack tubing. Movement arms are made of electroweld steel round tubing. The five-stage material prep/wash process is followed by an electrostatically applied, heat-cured powder coat. |
| Bearings and Pivot Points | Oversized, linear, re-circulating ball bearings run on case-hardened shafts and are sealed and self aligning. Pivot points and joints feature motor-grade sealed ball bearings, or sleeve bearings, utilizing either oil-impregnated bronze bushings or pre-lubricated nylon bushings. Bolts are grade 5 or above in all applications. |
| Pulleys and Cables | Glass-fiber-reinforced nylon pulleys provide strength and durability, while precision ball bearings allow effortless rotation. Cables use a 7x19 stranded wire configuration for added strength and flexibility and are coated with black pressure-extruded nylon for long lasting protection and a smooth feel. 3/16-inch (.48 cm) wire is coated to 1/4 inch (.64 cm) with a breaking strength of 4200 lb (1905 kg) and 1/8 inch (.32 cm) wire is coated to 3/16 inch (.48 cm) with a breaking strength of 2000 lb (907 kg). |
