The OG of the group
Featured product
Stability starts at the wrist. The 521 Static Strap anchors you cleanly to cable attachments, machines, and pulley systems with zero give and total control. Featuring a rugged steel D-ring and wide Velcro closure, this strap locks in fast and stays put — rep after rep, week after week. Inside, neoprene padding keeps things comfortable while the outer webbing does what it was built to do: hold strong under pressure.
American-made. Built for precision.
