Adjustable Positioning Lanyard Cowstail Series

The "Fish-Block" series of Adjustable Positioning Lanyards is specifically designed for rope access, industrial positioning, multi-pitch climbing, and aid climbing.

The entire series utilizes dynamic ropes compliant with the EN 892 standard, providing critical kinetic energy absorption and cushioning during accidental short-distance falls, significantly reducing the impact force transmitted to the human pelvis and anchor points. Featuring a precision-machined, anodized aluminum alloy "Fish-Block Adjuster," the system allows for rapid one-handed tightening or fine-tuning of the distance to the anchor. The side of the adjuster is specially designed with a dedicated eyelet for a release cord, enabling easy leverage-based rope release even when the system is under minor load or while suspended.

The full series is divided into two professional categories:

1. Industrial Heavy-Duty Version (10.5mm Dynamic Rope): Features a thick, highly abrasion-resistant rope body. It is compatible with the ventral attachment point of full-body harnesses and is capable of handling heavy-duty tasks such as uninterrupted protection while passing intermediate anchors and length adjustment for hand ascenders.

2. Sports Lightweight Version (9.2mm Dynamic Rope): Optimized for extreme weight reduction and handling flexibility, it is ideal for big-wall lead climbing, self-belaying at multi-pitch anchors, and rope system rigging.

Important Safety Warnings and Usage Limitations

• No Tear-Webbing Energy Absorber: This product is a positioning lanyard and is not a fall-arrest lanyard equipped with a tear-webbing energy absorber.

• Strictly No High-Limit Falls: Only for use in scenarios where the potential fall factor is less than 1 (Fall Factor < 1). The anchor point must always be kept at or above the level of the harness attachment point. Climbing above the anchor to create a high-factor fall is strictly prohibited!

• Rope Compatibility (Single Adjuster Accessory): The Fish-Block adjuster is only compatible with 8.5mm–11mm EN 892 certified single dynamic ropes.

Key Features

• EN 892 Dynamic Rope Cushioning: The industrial version uses 10.5mm dynamic rope, and the sports version uses 9.2mm dynamic rope. Both effectively absorb impact energy during low-fall-factor accidents to protect the human spine and anchor points.

• Ergonomic "Fish-Block" Adjuster: Lightweight forged aluminum alloy. Shorten the distance by simply pulling the rope outward with one hand; positioning is smooth and precise.

• Load-Release Accessory Cord Eyelet: The side of the adjuster features a micro-hole where an auxiliary cord or quickdraw can be pre-rigged to release the load under tension, preventing the device from locking up.

• Integrated Dyneema Soft Shackle (Single Adjuster Model): The single-head adjustment accessory comes pre-installed with a UHMWPE soft shackle, which transfers force in reverse to provide a more direct and responsive leverage for load release.

• Bi-directional Installation Compatibility: The length adjuster can be clipped directly to the ventral ring of the harness (for easy manual adjustment by the operator) or fixed in reverse at the anchor end (for remote adjustment by ground crew or a belayer).

• Modular Options for Various Scenarios:

  • Single-Head Model: For chest extension of hand ascenders and routine work positioning.

  • Double-Head Single-Adjuster Model: Fixed arm connects to the hand ascender/ascender, while the adjustable arm allows for passing intermediate transition nodes to achieve "continuous protection."

  • Single-Head Fully Adjustable Model: Offers the freedom to set the length of both the fixed and adjustable arms; tie a stopper knot to flexibly define attachment points—a versatile all-in-one solution.
