Y-shaped chest-lifting adjustable shoulder straps

A professional Y-type adjustable Chest Ascender Shoulder Strap designed specifically for Single Rope Technique (SRT), caving, tree climbing, and rope ascent systems. This product is intended for use in conjunction with a sit harness to securely position the Chest Ascender (Croll) on the golden load-bearing midline of the chest, preventing the ascender from sagging or flipping during ascent, thereby significantly improving rope-running smoothness and single-step efficiency when ascending with leg thrusts.

The main body of the strap is precision-sewn from high-abrasion-resistant, thickened polyester webbing, offering excellent wrinkle resistance, durability against friction, and resistance to water absorption and deformation. The chest area features an "extended-handle quick-adjust aluminum alloy buckle," paired with a finger-pull loop at the end of the webbing, allowing for instantaneous tightening or releasing of the strap tension with one hand, even while wearing heavy protective gloves in muddy or wet environments. The back is equipped with a quick-release buckle adjustment loop, allowing for flexible compatibility with various mainstream sit harnesses and chest ascender connection points.

Available in two dedicated versions:

1. Standard Buckle Version (approx. 103g): Compatible with the vast majority of conventional SRT caving and climbing sit harnesses.

2. ALP Dedicated Universal Version (approx. 113g): Specially adapted for ALP-structure harnesses, optimizing routing and load-bearing angles.

Important Safety Note

• Not PPE (Personal Protective Equipment): This shoulder strap is intended solely for positioning the chest ascender and adjusting posture. It has no fall-arrest or load-bearing capability and is strictly prohibited from being used alone for human fall-arrest suspension or load-bearing protection!

Key Features

• Vertical Chest Ascender Positioning: Ensures the chest ascender remains vertically flush against the chest, allowing the rope to pass through smoothly with each step, eliminating slack and rope drag.

• Extended-Handle Quick-Adjust Buckle (Glove-Friendly): Aerospace-grade aluminum alloy quick-adjust buckle with a specially designed extended lever handle, allowing for easy adjustment even with thick protective gloves.

• Webbing End Pull-Loop Design: A pull loop is specially sewn into the tail end, allowing for rapid tightening of the strap with a single-handed downward pull.

• Adjustable Back Buckle Loop: Flexible back structure is adjustable, precisely accommodating different brands' back connection points and body sizes.

• Ultra-Lightweight Design: Weighing only about 103g–113g, it can be worn for long periods without burden and folds down to palm size for storage.
