SpinRx Anchor Arm Swivel Raft-U

The SpinRx Anchor Arm Swivel – Raft-U provides independent rotation at the anchor tie-off point without requiring any drilling into the raft frame. It mounts securely using a supplied NRS-style U-bolt, allowing the anchor rope to rotate freely under load. When paired with the SpinRx Mini or Original Swivel Pulley, it completes a fully swiveling anchor system, eliminating rope twist from the pulley through the tie-off point and extending rope life over repeated anchoring cycles. Designed to fit 1-5/8” NRS-style tubing, the Raft-U features a low-profile, clamp-on design. All required stainless steel hardware is included.

• NO-DRILL INSTALLATION: Clamp-on U-bolt mount installs securely without frame modification.
