2. GENERAL SPECIFICATIONS 1. Frame Construction
• Frame is constructed of mechanical quality steel purchased in mill run quantities
• Frame is primarily 4” x 2” (10 cm x 5 cm) and 3” x 2” (8 cm x 5 cm) rectangular-shaped
tubing with 11 gauge wall thickness.
• Frames are mostly fully welded and constructed in two, but not mores than 3 pieces to
facilitate movement through smaller doorways and difficult installations
2. Frame Finish
• Prior to applying finish, each part is chemically washed to prepare surface for maximum
adhesion.
• The frames are coated with an electrostatic epoxy powder coat finish applied in a powder
form and then baked at 400° F (204° C.)
• To prevent frame and surface corrosion, wax equipment annually and keep away from salt,
chlorine and all other harmful chemicals.
3. Weight Selection
• Weights are selected by using a 7/16” selector pin, which completely penetrates the weight
plate and is held in place during use by a magnetic ring to keep the pin from disengaging
during use.
• The selector pin is connected to the top weight to eliminate loss or substitution of
substandard pins.
4. Incremental Weight System
• Incremental weight system allows the resistance to be increased in 5 pound increments and
are contained on the guide rods to eliminate removal.
• When in use, the increment weights retain the balance of the stack resulting in a smoother
action of the weight stack as compared to systems which load the increment on the side or
back of the actual stack.
5. Weight Plates
• Machined from solid, 1” thick steel. Finish is wrinkle gray powder coat. Thickness of plate is
held to precise tolerances by machining the entire upper and lower surfaces resulting in a
better pin fit to the stem.
6. Weight Plate Bushings
• Each plate (not just the top weight) will contain low friction bushings, which surround the
guide rods to minimize friction and noise
7. Top Weight Bushings
• The top weight runs on bushings which are mounted in the plate with rubber gromments to
compensate for minor misalignment and insure optimal performance.
• The bushings are self-lubricating in order that the guide rods will not require lubrication.
