Uneven wedge faces (offset nuts) or specialist cams (offset/micro) — exactly where normal gear finds nothing.

Placing cams
Placement tips
Cams hold by lobe friction in the crack. Best in the middle of the range — neither too open nor crushed. Makers (e.g. Black Diamond) often call about 50–90% retraction the ideal working range.
Angle clearly over about 90° → cam is probably too small. Take the next size up.If in doubt, slightly too big (right) beats too small (left) — too small is the more dangerous mistake.
Angle of the lobe undersides
Look at the angle between the straight undersides of opposite lobes (see photo). Clearly over about 90° usually means the cam is too small (too open) — take the next size up. Good is flatter, roughly toward ~60° or below.
Slightly too big beats too small
Between a bit too open and a bit over-cammed, pick the slightly larger size. Too small can skate in a fall — too big often still holds, it’s just harder to retrieve. Still avoid being fully crushed.
Middle of the range
Ideal: about 50–90% retracted. Dead centre is nice — if in doubt, a bit more retracted than too open.
Load direction
Align the stem with the expected fall. A sideways pull can twist or lever the cam out — especially in horizontals.
All lobes on rock
All three/four lobes should sit evenly on solid rock — not on brittle crystals, edges, or in holes that only two lobes touch.
No crack that opens down or behind
Cracks that open up or behind the cam invite walking. Slightly constricting or parallel spots are better. Extend with a draw/sling if needed so the rope tugs the stem less.
Rock quality
Cams press outward — loose, wet or mossy rock holds worse. Tap, look, place only in solid rock.
Guess the size with your hand
Good drill on the ground or in the gym: put a hand in the crack/slot and guess the cam size before you grab it. Switching costs time and power — hitting the size first means faster, calmer placing.
Cams walk
Sideways wobble (rope drag, climbing over) walks cams deeper into the crack — then they’re almost stuck. Extend with a draw/alpine draw so the rope tugs the stem less.
Slightly uneven camming is fine
The lobes don’t need millimetre-equal opening. Slightly different camming is fine — as long as all sit on solid rock and nothing dances on an edge.
Sometimes rotate 180°
Rotate the cam once around its stem — it often sits better, especially in irregular cracks.
Two axles, not one
Double-axle cams (Camalot & co.) sit more stably — like a wall plug that expands. Single-axle cams can over-rotate. Buy double-axle, except the tiniest (those may be single-axle).
Rock: granite vs. limestone
On granite (and other crystalline rock) lean cams. On limestone more nuts — V-spots and pockets are more common there than clean parallel cracks.
Placing nuts
How to place nuts
Nuts (stoppers) are passive wedges: they hold because the shape pinches in a V — not because springs cam. Size, contact and always a draw or alpine draw matter.
Bad: little contact on one side — nut too big or not in the pinch. Pick another size.Bad: carabiner only — rope movement can unseat the nut.Good: alpine draw instead of a carabiner only — the sling damps movement, the nut stays seated.
V-shaped constriction
The spot must pinch in the load direction and match the wedge. Parallel cracks → a cam. Wrong shape = the nut skates or holds on one edge.
Lots of contact on both sides
As much face on the rock left and right as you can. Only the bottom edge / one side in contact (see photo) → too big or a bad pick; it can twist out and pop.
Change size until it sits
That’s why you carry a full set: too big rattles, too small slides through. The right size feels seated before you set it.
Set it firmly
After placing, pull firmly in the load direction so the wedge seats. Unset, it walks as soon as you climb over it.
Always with a draw or alpine draw
A carabiner alone on the nut is not enough: as you climb on, the rope puts a lot of movement and force on the wedge — it can unseat. Always extend (alpine draw or quickdraw) — the soft sling damps the movement.
Watch the load direction
The wedge must pinch against the expected load. Sideways pull or “wrong way” in the slot — check the placement before you move on.
Prefer the lower part of the pinch
Seat nuts in the lower part of the constriction, not on the lip at the top. Up there they often sit on a rim and pop more easily.
Is the block solid?
One hand on the block, tap with the other. If you feel vibration, it isn’t solid — no sling or cam on it.
Extending
Alpine draws
If the rope line leaves the vertical (zigzag through gear, corners, overhanging edges), extend with alpine draws. Otherwise rope drag eats you — and nuts can walk from rope movement.
Bad: the rope yanks around corners and through short draws — massive drag. Extend with alpine draws so the line runs smoother.Good: alpine draws extend the pieces — the rope runs freer, less drag, calmer climbing on.
Alpine draws against rope drag
Short sport draws yank the rope hard into every piece. Alpine draws (sling + 2 carabiners) let the line run smoother — less drag, easier clipping higher up.
Build your own
60 cm sling + 2 carabiners: thread one through the other and clip back. Pull on one of the three strands — the draw extends.
Tape the lower carabiner
Like sport draws: hold the rope-end carabiner with tape or a clip so it doesn’t flip when you clip pumped.
Leading
Routes, learning & strategy
Good beginner routes
As a beginner, only well-protected lines (G / no R/X). Better a 5.9 hand crack with lots of gear than a “easy” 5.6 slab with runouts — old grades are often sandbagged.
Near the ground: place dense
Don’t skimp in the first metres. Place tight — avoid a ground fall even if the last piece rips.
2–3 pieces before a dicey bit
Before a hard or risky passage (crux, runout, loose) place 2–3 pieces close together. If one rips, the others still hold the fall high enough.
Place a size you still have two of
If you can, place a size that still has a twin on the harness. Save the “last” size for the spot where only that one fits.
Not too little, not too much
Stay safe, but don’t place so much that nothing is left for the anchor. Strategy: denser where it’s risky, leaner where it’s calm.
Top-rope first, then lead
Before you lead: climb the route on top-rope and practise placing (pick size, set, clip). Know the moves and placements — then the lead feels much calmer.
Go with more experienced climbers
Second, look at placements: why a nut not a cam, why this size, why this crack. Best way to learn — besides practising on the ground.
Practise on crystalline rock
Learn the cam feel on gneiss, granite, porphyry rather than smooth limestone. Nearby: Battert (easy grades), Murgtal / Ergenfelsen near Gernsbach (two cracks), Brettfels (Pumprisse).
Aiding slings in cams
To cheat / rest: knot a sling in the cam and use it as a step. Only where allowed or marked p.a. — and check the cam afterwards; it walks under foot load.
Footwork
Don’t put a leg behind the rope
Above the last piece the rope must run on the laces side of the foot — not behind the leg. Otherwise a fall can flip you upside down.
Bad: leg behind the rope — risk of flipping in a fall.Bad: after standing up often worse — rope behind the leg. Get it onto the laces side immediately.Good: rope on the laces side — in front of the foot, not behind the leg. That’s how you stay upright in a fall.Good: standing too — rope stays in front at the laces. That’s the goal after you stand up.
Rope on the laces side
Foot in the crack: rope in front at the laces, not behind the calf. It can look crossed — but it keeps you upright in a fall.
Standing up is the critical moment
Down low it can still look fine — as soon as you stand, the leg is often suddenly behind the rope (see photos). Check and correct before the next move.
Belay stance
Trad stance with cams
On solid bolts: a DAV series anchor (see belay anchors). In a crack without bomber bolts: often equalise three good cams or nuts — a long sling shares the load across all points.
Three cams, long sling equalised, overhand as master point — a carabiner sits in the knot so it undoes more easily later.
Three good pieces
Classic: three solid cams/nuts in the expected load direction. Test each piece — a “nearly good” point doesn’t count.
Equalise with a 240 cm sling
Clip the sling into all three carabiners, gather the inner strands and equalise in the load direction. Tie an overhand as the master point — all three pieces then share.
Carabiner in the overhand
Before you cinch the overhand: put a carabiner through the knot. Later the knot is much easier to undo — otherwise it often welds after loading.
Rope as a fallback
No long sling? With the climbing rope: clove hitch outside, master-point knot, clove hitch other side — equalised, plus a tether on the rope.
A tree only if it’s solid
Alive, thick, healthy. Sling around the trunk, knot so you have redundancy (one side fails → the other still holds).
Usually a soft catch like sport. On a runout with ground or ledge risk, catch hard and take in slack — a hard catch beats a ground fall.
Knots in the rope ends
When rappelling always knot the ends. Practical: one overhand through both ends together (lots of tail) — they stay together when thrown, less “one end stuck up there”.
Check fear and desire honestly
Fear is normal. If the fear feels like fire and you can’t come down, you may not be ready — better to bail than talk yourself into it.
No complacency
Experience brings confidence — and the risk of getting sloppy (placing less, leg behind the rope, sloppy belay). Stay careful and humble.
Clean climbing & nature
After rain on sandstone often wait 48–72 h. Don’t overcam. Clean shoes against polish. Don’t step on crypto soils. Pack poo out in a bag, don’t bury it.
Fine debris on the boulders
Fine small stones on the boulders at the base are a clue of rockfall. Helmet on; don’t belay needlessly under loose ground.
