Zigco SpinRx Anchor Arm Swivel - Raft

Zigco proudly introduces the SpinRx Anchor Arm Swivel – Raft-U . This product provides independent swivel performance at the anchor arm tie-off point without requiring any drilling into the raft frame. Designed to mount directly to 1-5/8” NRS-style tubing using a supplied stainless steel U-bolt, the Raft-U allows the anchor rope to rotate freely under load, eliminating rope twist and reducing binding. When paired with the SpinRx Mini Swivel Pulley or Swivel Pulley , it completes a fully swiveling anchor system from pulley to tie-off point. Manufactured from aerospace-grade aluminum and supported by a sealed stainless steel bearing and hardware, the SpinRx Anchor Arm Swivel – Raft-U delivers reliable performance in a low-profile, clamp-on design built for demanding environments. PRODUCT FEATURES NO-DRILL INSTALLATION: Clamp-on U-bolt mount installs securely without modifying the raft frame. ELIMINATES TIE-OFF ROPE TWIST: Independent swivel allows rotation without twisting the rope. COMPLETES THE SPINRX SYSTEM: Pairs with SpinRx Swivel Pulley for full-system rotation. FITS NRS-STYLE TUBING: Designed for 1-5/8” raft frame tubing with a clean, low-profile fit. EXTENDS ROPE LIFE: Reduces fatigue caused by repeated torsional loading. CNC MACHINED ALUMINUM: Precision machined from solid aerospace-grade aluminum for strength and durability. SEALED STAINLESS BEARING: Smooth, maintenance-free rotation with excellent corrosion resistance. HARD ANODIZED FINISH: Enhanced wear and corrosion resistance with a lightweight profile.
