Mammut - Nordwand Alpine Belay - Black - Belay Device

• Best for:
  • Alpine climbing
  • Multi-pitch
  • Mountaineering
  • Trad climbing

Why we love it

The Nordwand Alpine Belay is built for the long haul – a tube-style belay device and descender that handles the full range of alpine rope work without the weight penalty. The V-shaped grooves and rear rope-bearing surfaces are made from abrasion-resistant steel, so the device resists the wear that eats aluminium tubers over time, and the steel insert helps keep it from overheating on long rappels. The aluminium housing keeps the total weight to just 80 g. Guide mode allows an auto-blocking setup when belaying followers from above, and the wide 7.5–10.5 mm range covers thin half and twin ropes through to standard single ropes – so one device covers the whole rack on a multi-pitch or alpine route.

Tech Specs

• Type: Tube-style belay device and descender – with guide mode
• Weight: 80 g
• Rope compatibility: Single, half, and twin ropes 7.5–10.5 mm
• Materials: 90% aluminium, 10% steel

Features

• Steel Rope-Bearing Surfaces: V-shaped grooves and rear rope-bearing surfaces in abrasion-resistant steel – resisting the wear that shortens the life of all-aluminium devices.
• Heat-Resistant Steel Insert: The steel insert helps prevent the device overheating during long or repeated rappels.
• V-Shaped Grooves: Grooved geometry increases friction for controlled braking and lowering with reduced hand strain.
• Guide Mode: Allows an auto-blocking setup when belaying one or two followers directly from the anchor.
• Lightweight Aluminium Housing: Keeps total weight to 80 g despite the steel wear surfaces.
• Wide rope range: Handles thin half and twin ropes through to standard single ropes – one device for the full spread of alpine and multi-pitch use.

Safety

• Certifications: CE EN 15151-2 – personal protective equipment (PPE); UIAA
