Ascenders and descenders are integral components of the FORT mountaineering gear series, dedicated to providing safe and reliable solutions for climbing and high-altitude operations. Our products adhere to CE standards and the CE own brand lable is accessible, ensuring users can ascend and descend safely in any environment. We are actively seeking outstanding partners worldwide to become local agents for FORT. If you are interested in becoming our partner, please contact us and let's build the future of safe climbing and high-altitude operations together.

As a professional climbing equipment manufacturer, NAL HON Industrial offers various rope climbing safety equipment parts for working at heights, and rock climbing to protect humans from fall damage such as climbing hooks, safety carabiners, D-rings, safety buckles, dielectric parts, rope grabs, beam anchors, tripod anchors(fall arresters)/SRLs, zipline pulleys/swivel connectors, rescue ascenders/descenders, etc.

We supply hardware matched to the mechanical and environmental demands of four core application areas. In our engineering process, we prioritize structural integrity, durability under repeated stress, and compliance with international safety standards, helping users stay protected in high-risk work environments.

We focus on design and test our equipment to meet sector-specific criteria:

• Mountaineering—Certifications: UIAA, EN 12275, CE Marking. Strength: major axis ≥ 20 kN, minor axis ≥ 7 kN, gate-open ≥ 6 kN. Focus: resistance to ice, moisture, and sudden dynamic loads.
• Rock Climbing—Certifications: EN 12275, EN 566 (slings), UIAA. Strength: major axis ≥ 20 kN, minor axis ≥ 7 kN, gate-open ≥ 6 kN. Focus: long-term wear resistance and smooth gate operation.
• Fall Protection (Industrial)—Certifications: EN 795, ANSI Z359, OSHA 29 CFR 1926 Subpart M. Strength: minimum static strength ≥ 12 kN; anchorage safety factor ≥ 2× rated working load. Focus: traceability, documentation, and reliability under high-energy fall-arrest events.
• Rescue Operations—Certifications: NFPA 1983, EN 341, EN 1496. Strength: multi-person system load typically ≥ 40 kN. Focus: multi-user, high-capacity scenarios.

Materials & validation: all hardware uses high-strength aluminum alloy or stainless steel, and is validated through tensile, fatigue, drop/impact, and salt-spray/humidity corrosion testing.
