The Ascender - Chest by Diving Magnets (Pty) Ltd is a professional-grade accessory designed for commercial diving operations. Built with marine-grade materials for long-term durability in demanding subsea environments.
The Chest Ascender is a compact and durable rope-gripping device designed for efficient rope ascent during climbing and rope access operations. Constructed from high-strength aviation aluminum alloy, it offers excellent durability while remaining lightweight and easy to handle. Its compact ergonomic design allows smooth upward movement on the rope while automatically locking securely when downward force is applied, ensuring reliable safety during vertical work.
The ascender features upper and lower attachment slots for connecting carabiners or additional equipment, making it ideal for integration into rope access or climbing systems. A spring-loaded cam mechanism allows easy one-handed operation while maintaining strong rope engagement in demanding conditions.
Specifications: Rope compatibility: 8–13 mm | Material: Aviation aluminum alloy | Size: approx. 11.6 × 7.0 cm | Weight: 158 g | Color: Red | Certification: CE1019, EN567.
Suitable for climbing, rope access work, aloft operations, engineering applications, and caving.
Frequently Asked Questions
What is the actual pull force of the Ascender - Chest underwater?
The Ascender - Chest is rated at its stated rating on a clean, flat, mild steel surface. Underwater, real-world pull force depends on surface condition (rust, paint, marine growth), surface thickness, and contact angle. Expect 50–80% of rated pull on typical subsea steel structures. Always use a 2–3× safety factor for dynamic loads.
How long will the Ascender - Chest last in saltwater?
With proper care — rinsing with fresh water after each use and drying before storage — the Epoxy-HDPE coating protects the neodymium core for 4+ years of regular commercial diving use. The 316 stainless steel hardware is highly resistant to saltwater corrosion. Avoid dropping the magnet on hard surfaces, as impact damage to the coating is the primary cause of premature corrosion.
Is the Ascender - Chest strong enough for commercial diving?
Yes. The Ascender - Chest at its rated pull force is designed for light-duty commercial work including inspections, surveys, and small tool holding. If you regularly work with heavier tools or in strong currents, consider stepping up to a higher-rated model.
What surfaces does the Ascender - Chest work on?
The Ascender - Chest works on any ferromagnetic surface — mild steel, carbon steel, cast iron, and structural steel provide the best results. Performance is reduced on rusty, painted, or curved surfaces. It will not work on aluminium, brass, copper, most stainless steels (304/316), concrete, wood, or plastic.
Can I use the Ascender - Chest for lifting?
No. The Ascender - Chest is designed for horizontal tool holding and equipment staging — not for vertical lifting or rigging. It is not certified lifting gear. For safety-critical applications, always use rated lifting equipment. The magnet is a positioning and holding tool, not a load-bearing device.
