Body-Solid GKR9 Vertical Knee Raise and Dip Attachment for the G9B Gym

Body-Solid GKR9 Vertical Knee Raise and Dip Attachment

The GKR9 bolts a vertical knee raise and dip station onto the side of a Body-Solid G9B gym. It adds two bodyweight movements the gym does not otherwise cover, and it lets a third person train while the two weight stacks are in use. It carries no weight stack of its own.

Fits: the Body-Solid G9B multi-station gym. Body-Solid also lists this part as the GKR9B on its current G9B page. Same attachment.

What does the GKR9 add to a G9B?

• Vertical knee raises. Supported on the back and arm pads, so you work the abs and hip flexors without hanging from a bar.
• Parallel bar dips. Chest, front delts and triceps, loaded with your own bodyweight.
• A third training station. Because it uses no cable and no stack, someone can use it while both weight stacks are busy.

How much extra room does it need?

The attachment itself measures 26.9 in. long by 47.3 in. wide by 74.8 in. tall and mounts to the side of the gym frame. Add its width to the side of the G9B you mount it on, and leave standing room in front of the dip handles.

How is it built?

• Oversized contoured back pad with arm pads and hand grips
• Steel frame finished to match the G9B
• Assembled weight 84.5 lb.
• No weight stack and no cable connection
