Ordering a Cuff Exchange:  We can definitely do a cuff exchange for you! We charge $15 to $30 for exchanges to cover our shipping and processing cost based on your address. We can create an online invoice for you payable online. Once the invoice is paid, we will send you the new set of cuffs and include a pre-paid return shipping label.    Exchanging Out Your Old Cuff  To exchange your old cuffs for the new ones, first completely unscrew the black angle adjustment wingnut and remove the old cuff from the leg assembly. Please note that we've marked the grips on the new cuffs as either “left” or “right”. Then reattach the new “left” cuff to the “left” leg and tighten down the black angle adjustment wingnut. Repeat for the right cuff. The old cuffs then go back in the box. Apply the included return shipping label over top of the original shipping label. Then just ship the box back to us. If you have any questions please reach out!
