Harken 13mm High-Load Trolley w/2X M4 Tapped Holes

The Harken 13mm High-Load Trolley with 2X M4 Tapped Holes is a precision linear motion component engineered for demanding tactical, military, and industrial applications where reliable load transfer is non-negotiable. This compact trolley serves equipment rigging systems, hoisting setups, and modular load-bearing assemblies where smooth, consistent travel and corrosion resistance directly impact operational reliability. Whether you're outfitting a mobile command platform, securing heavy gear during transport, or building custom rigging infrastructure, this trolley delivers the low-friction performance required in high-consequence environments.

Built around recirculating ball bearings housed in lightweight aluminum, the Harken trolley minimizes friction while maintaining exceptional load capacity across repeated cycles. The aluminum construction provides inherent corrosion resistance—critical for field storage, humid climates, and saltwater exposure—without sacrificing strength or weight efficiency. The two M4 tapped holes enable direct integration into existing mounting systems, tactical rails, or custom fabrication projects, allowing you to anchor this trolley precisely where linear motion is needed. At just 0.15 lbs with a compact 2 x 1 x 3-inch footprint, it adds negligible weight while handling serious loads silently and smoothly.

Operators, engineers, and armurers benefit most from this component when building custom equipment carriers, cable-driven load systems, or adjustable rigging for vehicles and shelters. The M4 tapped holes integrate directly with metric fasteners and NATO-standard mounting patterns common in military platforms and tactical equipment. Installation is straightforward—secure the trolley to your mounting surface, route your load line or cable through the bearing track, and the recirculating ball design ensures years of dependable, quiet operation. For teams requiring modular, corrosion-resistant linear motion in compact form, this Harken trolley delivers professional-grade reliability at field-proven specifications.
