Ronstan Series 40 Orbit Single Block w/Becket & Swivel Head

The Ronstan Series 40 Orbit Single Block with Becket & Swivel Head is a precision rigging component designed for vehicle recovery, marine applications, and mechanical advantage systems where controlled load management is critical. Whether you're setting up a winch line, securing cargo during transport, or managing rope tension in a complex mechanical setup, this single block delivers the reliability and durability that professionals demand. The compact 2-inch footprint makes it ideal for tight engine bays, trailer configurations, and custom automotive builds where space is at a premium.

Ronstan's Series 40 engineering incorporates a swivel head design that eliminates rope twist and binding—a critical feature when managing dynamic loads during vehicle recovery or towing operations. The integral becket provides a secure attachment point for secondary lines or safety hardware, while the single-pulley configuration minimizes friction loss and simplifies installation compared to multi-block systems. At just 0.15 pounds, this block adds negligible weight to your rig, making it perfect for weight-conscious builds, overlanding setups, and auxiliary recovery kits. The compact dimensions (2 x 2 x 2 inches) allow seamless integration into custom brackets, winch fairleads, or mechanical systems without consuming valuable real estate.

This block is ideal for vehicle owners building DIY recovery systems, mechanics assembling custom winch configurations, and enthusiasts upgrading their automotive or trailer setups. The swivel head design is particularly valued in applications where rope rotation must be controlled—critical when working with synthetic winch lines or managing load angles in recovery scenarios. Its lightweight construction and minimal profile make it essential for truck beds, engine compartments, and fabricated mounting systems where every inch and ounce count. The Ronstan Series 40 Orbit Single Block delivers professional-grade performance for serious automotive and mechanical projects requiring reliable load management.
