View shows attachment points, with hand cycle attached. Very important that they do not interfere with regular function of the chair. This is my full time wheelchair, with or without the hand cycle attached.

Leaving the tubes free spinning allows for easier attachment by person using the wheelchair. Notice the weld ring on the attachment tube, this accident created a nice stopping mark, keeping the tube from sliding to far into the attachment tube on the wheelchair.
Four 2in tube sections were welded to the chair creating the attachment points. Two on this side, two on the other.
