{"product_id":"njtx-155","title":"Assisted braking multi-purpose climbing belay and rappel device","description":"\u003cp\u003eA lightweight and compact multi-functional assisted braking belay device designed for lead belaying, top-rope belaying, and single-rope controlled rappelling.\u003c\/p\u003e\n\u003cp\u003eThe overall structure balances ultra-light weight with durability. The housing is made of high-strength 7075 aerospace aluminum alloy, while the internal critical load-bearing cam and rope friction components are crafted from specialized hardened steel, which resists groove wear even under high-frequency rope friction. Feeding and taking in rope is smooth and responsive; when a climber falls or the main rope experiences sudden tension, the internal eccentric cam automatically rotates to clamp and lock the rope, providing critical assisted braking protection.\u003c\/p\u003e\n\u003cp\u003eWhen controlling a descent, the ergonomic handle allows for progressive fine-tuning of the rappel speed; releasing the handle causes it to automatically spring back to the reset position and lock. The Black Shield model is specially equipped with a \"folding handle\" structure, which allows it to sit flush against the device body when stored, significantly reducing the space it takes up on a harness or inside an equipment bag. The housing features clear laser-engraved rope installation diagrams to prevent backward threading. The device weighs only about 153g, has an industrial-grade safe working load of 150kg, and has passed the authoritative XF494-2023 inspection standard.\u003c\/p\u003e\n\u003cblockquote\u003e\n\n\u003cp\u003e\u003cb\u003eCore Safety Warning (Braking Hand Rule)\u003c\/b\u003e\u003c\/p\u003e\n\n\n\u003c\/blockquote\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eNever let go of the brake-side rope\u003c\/b\u003e: Whether lead belaying, top-rope belaying, or rappelling with the handle, \u003cb\u003ethe brake-side rope must always be held in the palm of your braking hand\u003c\/b\u003e.
