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

Tibloc
Petzl
The Petzl Tibloc is an ultralight emergency ascender and rope clamp that has become an essential safety component for alpinists, ski mountaineers, and rescue kits. Weighing roughly 35 grams, it takes up practically no space on a harness rack. The device utilizes an angled, spring-loaded plastic rocker that presses the rope directly against the carabiner spine, ensuring that the stainless steel teeth engage the rope sheath immediately upon loading without slipping. In practical field situations, the Tibloc shines as an emergency tool. It is widely used to ascend fixed lines during self-rescue, build mechanical advantage systems for crevasse extraction, or act as a progress capture clamp when hauling packs over cruxes. Its ability to handle standard single ropes down to skinny alpine cords makes it exceptionally versatile across diverse mountain disciplines. The Tibloc is not designed to replace standard handled ascenders for routine big wall jugging. Because it forces the rope teeth into the sheath via carabiner pressure, improper alignment or dynamic slippage can damage rope sheaths. It also offers zero ergonomics for extended hauling or continuous ascending. As an insurance policy kept on a harness loop, however, its balance of weight and function is virtually unmatched. **Highlights** - Extremely lightweight at approximately 35 grams - Spring-loaded rocking plate ensures immediate cam tooth engagement - Compact profile takes up negligible harness or pack space - Compatible with a wide range of rope diameters - Ideal for crevasse rescue rigs and emergency rope ascending **Watch-outs** - Not intended for extended, continuous rope jugging - Improper carabiner pairing or poor technique can cause sheath damage - Lacks any ergonomic grip for comfortable handling

- Integrated sub-step and grab loop maximize reach on high placements
- Reinforced step inserts help maintain loop openings against the wall
- Alternating offset design induces foot twist and calf fatigue over long leads
- Lacks full rigid spreaders, making entry harder in high winds
- Heavier and bulkier on the rack than modern ultralight ladder styles
Tibloc
- Ultralight 35-gram profile takes up negligible harness space
- Spring-loaded rocker plate ensures instantaneous tooth bite without slipping
- Aggressive stainless steel teeth grip reliably on wet or frozen ropes
- Far less expensive than full progress capture pulley systems
- Can severely damage rope sheaths if loaded dynamically or misaligned
- Requires specific round-profile carabiners for safe, predictable engagement
- Lacks an ergonomic handle, making sustained ascending slow and fatiguing
