General Specifications

1.Frame Construction

Frame is constructed of mechanical quality steel purchased in mill run quantities. Frame is primarily 2 ½" x 4 ½" oval-shaped tubing with 11 gauge wall thickness.

2.Frame Finish

Prior to applying finish, each part is chemically washed to prepare surface for maximum adhesion.

3.Weight Horn

Weight horn under the head pad gives users the ability to increase resistance with Olympic weight plates. This allows flexibility for all users in all phases of their training.

4.Cam

The cam is CNC machined from solid polymer and designed to match the appropriate muscle strength capability curve.

5.Integral Bearings

Bearings are sealed bearings with a basic radial load rating of over 2,000 pounds. Bearings are mounted within precision-machined housings for optimal alignment, which results in smooth and friction free movement.

6.Bolts

All hardware is metric and has a corrosion resistant finish.

7.Upholstery Contoured pads.

All edges are stitched to eliminate any folds in the material that would limit durability.

8.Foam

Three and four pound EVA foam (deformation resistant) or equivalent is used on all machines. The foam is injection molded directly to the multi- ply wood support board with integral 10mm T-nuts.

9.Hand Grips

Hand grips are an extruded 60-durometer-thermorubber compound that is non-absorbing, wear and tear resistant, and exhibits good dry and wet frictional characteristics.

The grips are retained with aluminum collars, which eliminate the tendency of the grips to slide off the handle.

10.Foot Platforms

Foot platforms are molded rubber with a slip resistant texture.
