Black Diamond
The Black Diamond Index is a full-featured handled ascender engineered for jugging fixed lines, cleaning pitches, and hauling loads on big walls. Available in right- and left-handed configurations, it stands out for its release trigger mechanism. Unlike traditional ascenders that require a clumsy two-handed or high-friction maneuver to back the cam off a loaded rope, the Index uses a dedicated trigger accessible with an index finger, facilitating one-handed operation when bypassing knots or adjusting position. Performance on the rope is smooth and consistent. The toothed stainless steel cam provides immediate bite on clean cords as well as dirty, iced, or muddy ropes. The body of the ascender features a large, dual-density molded grip that cushions the palm and accommodates bulky winter gloves without pinching. A generous carabiner clipping hole at the base accepts multiple locking carabiners for daisy chains and foot loops, while the upper clipping hole keeps the unit aligned on the rope when needed. At roughly 200 grams per unit, the Index is heavier than minimalist, handle-free rope clamps. It is also more expensive than basic models. However, climbers who routinely jug hundreds of feet of fixed rope will find the ergonomic handle and effortless trigger release well worth the weight penalty and price premium. **Highlights** - Index-finger trigger allows smooth, one-handed cam release - Aggressive toothed cam bites securely on icy, wet, or muddy lines - Large dual-density grip accommodates thick mountaineering gloves - Dual clip-in points at the base easily accept multiple carabiners - Available in dedicated right- and left-hand models **Watch-outs** - Heavier and bulkier than compact emergency rope clamps - Premium price point compared to basic handled competitors

5 Step Aider
Metolius
The Metolius 5 Step Aider is an accessible, hard-wearing etrier built for climbers looking for proven functionality at an approachable price point. Constructed from heavy-duty one-inch nylon webbing, it uses a classic alternating-step design. For climbers beginning their aid journey or needing a reliable set of stirrups for occasional wall climbs, this aider delivers dependable performance without requiring the financial investment of specialized big wall ladders. Each step features Metolius’s reinforced construction, which helps the rungs stay open rather than collapsing flat against the wall. The top of the aider includes a dedicated sub-step and grab loop, giving climbers the leverage needed to gain maximum height out of high gear placements. The durable webbing stands up well against rough rock and repeated boot scuffs over multiple seasons of use. Because it relies on an alternating offset pattern rather than a centered ladder design, users will notice more lateral foot twist and increased calf fatigue during long, multi-hour hanging belays or multi-pitch leads. Additionally, the webbing lacks the full rigid spreaders found on premium ladders, making boot entry slightly less consistent in windy conditions or on free-hanging terrain. For budget-conscious climbers, it remains a durable workhorse. **Highlights** - Affordable entry-level price point for technical aid climbing - Durable one-inch nylon webbing resists rock abrasion - Reinforced steps hold their shape better than unlined webbing - Integrated top sub-step assists with high-reach placements - Built-in grab handle for secure balance near the top **Watch-outs** - Alternating step design causes more foot rotation than centered ladders - Steps lack full internal rigid spreaders, occasionally collapsing in wind
