TRANGO Aries Belay Device | Guide Mode, 7.5–11mm Rope, 7075 Aluminum

The TRANGO Aries Belay Device is a guide-mode belayer designed to help climbers manage rope work with confidence as they navigate challenging terrain. Crafted from hot-forged 7075 aluminum, Aries blends durability and lightness for long days on the rock, and it arrives with the Regulock HMS Autolock to provide a ready belay companion for various setups.

Enhanced braking control

• Dual V Channels for Controlled Braking: The dual V-channel design provides precise friction control for lowering and catching, helping you maintain steady rope handling on single-pitch or multi-pitch climbs.

Direct belay from anchors

• Guide Mode for Direct Belay: Enable belays directly from anchor points, ideal for bringing up seconds on multi-pitch routes, alpine climbs, and mountaineering objectives where top-rope belaying is useful.

Durable yet lightweight construction

• Hot Forged 7075 Aluminum Construction: Strong and light, approx 90 g for all-day comfort without bulk on your harness.

Rope compatibility

• Wide rope compatibility: Works with rope diameters from 7.5 mm to 11 mm, supporting single, half, and twin rope setups across sport, trad, ice, and alpine climbing.

Built for climbers, by climbers, Aries reflects decades of field testing and collaboration with the climbing community. The design aims to feel intuitive when you switch between belay and control, while remaining robust in variable weather and high energy demands on long routes.

With Aries, you gain a configurable belay workflow that suits a range of climbing scenarios, from fast-moving sport routes to complex alpine objectives. The inclusion of the Regulock HMS Autolock helps you set up a reliable anchor system quickly, giving you more time to focus on the climber’s progress and overall safety checks. While outcomes depend on technique and conditions, Aries presents a dependable option for climbers seeking predictable braking, versatile rope handling, and multi-pitch capability without unnecessary gear fuss.

What to expect on your next climb

Whether you are toggling between belay positions on a distant crag or coordinating a team from an anchor, Aries is designed to stay secure and easy to operate. The device’s engineering supports steady control during lowering and catching, with a streamlined profile that sits comfortably on a harness and remains accessible when rope work intensifies.
