Notch Rope Logic Ultra Rigging Block Sling 3/4in Tenex-Tec (40151) – Adjustable, High-Strength Rigging

Overview

Explore the Notch Rope Logic Ultra Rigging Block Sling in its dedicated block version. Built with 3/4" Samson Tenex Tec rope, this sling carries a rigging block that sits securely in the terminal eye. The design emphasizes compact, streamlined rigging so you can deploy the setup quickly in tight spaces. Length is adjustable through six evenly spaced 8" pockets, enabling you to fine‑tune the span without rewrapping or rethreading.

Key benefits at a glance

• Integrated rigging block captured in the terminal eye, reducing parts and setup steps.
• Six 8" pockets provide repeatable, controlled length adjustments along a 6' usable length (7' overall).
• 12‑strand 3/4" Samson Tenex‑TEC rope delivers high strength with relatively low stretch under load.
• Optimized for choked configurations and broad compatibility with common rigging blocks.
• High performance ratings: 21,000 lbs tensile strength and a 2,100 lbs working load limit.

Real‑world use and practical considerations

In field setups or workshop environments, the block‑in‑eye design helps keep gear organized and ready for action. The tactile rope construction provides a confident feel as the line tightens and settles, while the six pockets offer clear, repeatable reference points for length changes. This configuration can be particularly useful when you need a compact, predetermined reach that remains consistent across adjustments.

Compatibility and fit

Designed for choking configurations, the sling is compatible with a wide range of standard blocks. While not universal, several popular blocks have been tested for fit and reliable operation. Always verify your specific block combination before use to ensure safe performance.

Block compatibility highlights

Blocks verified to fit include CMI RP130, RP131, RP145; DMM Large (3/4" with hole) and Small (5/8" no hole); ESA 3/4"; ISC Red & Blue Rigging blocks (RP055, RP054, RP053, RP052, RP051, RP050); Flame RP056; Stein 5/8" Block. Note there are exceptions: CMI RP146 (1" Blue) and ISC RP57 (Yellow).

Care and maintenance

Inspect the pockets and terminal eye for wear after use. Store away from sharp edges and abrasive surfaces, and retire the sling if you notice any deformation or fraying. Following these steps helps preserve performance over time while you rely on predictable, repeatable rigging behavior.
