As far as I know, you can't get these anymore, but they're a great tool for use at the gym if you're letting a tired grip hold you back on heavy pulls (Pulldowns, Shrugs, Deadlifts, Rows, etc.).
These are heavy duty steel (and nylon) and are rated up to 650 pounds.
Shipping will be $10 in the continental USA and I'll ship either via FedEx, UPS, or USPS (depending on which place I'm stopping that day).
Any questions, please ask prior to bidding/buying.
Thanks!
