TL;DR: Bent gate goes on the rope end of a quickdraw, where the curve helps you clip faster on sport routes. Keep it off bolt hangers and anywhere you’d otherwise want a locker. A bent gate on a bolt hanger can hook the hanger during a fall and unclip itself from the wall. That’s not theoretical.
The Shape That Changes Everything (and Why It Only Works One Direction)
The curve on the gate does one job: it funnels the rope. Push a rope against a straight gate and it can slide along the gate’s length before anything useful happens. A bent gate makes a cradle. The rope drops into the apex, concentrates the inward push, and pops the gate open with less effort from your fingers.
That geometry only works one way. The same curve that invites a rope in will happily let something else out if you load it wrong. The whole design assumes the rope is sitting cleanly in the bottom basket.
Three features define a modern bent gate:
- The curve — anywhere from subtle (BD HotForge) to aggressive (DMM Alpha Sport).
- The nose — usually Keylock, so the rope doesn’t catch when you’re cleaning.
- Gate tension — often tuned slightly softer than a straight gate so the rope seats faster.
The One-Sentence Rule — Rope End Only
Bent gates belong on the rope end of a quickdraw. Put one on the bolt, and you’ve introduced a fall-unclip risk that’s been reported on Mountain Project more than once.
Here’s the mechanism. When you take a lead fall, the dogbone whips. If a bent gate is clipped to the bolt, the inward curve of the gate can hook over the edge of the hanger. The rope comes tight, pulls the draw downward, and the hanger acts as a lever against the curve, prying the gate open. Carabiner leaves the wall.
A straight gate presents a flat surface to the hanger, so there’s nothing for the hanger to catch. A bent gate gives it a concave hook that happens to match the edge of a standard 3/8″ or 10mm hanger almost perfectly. Bad geometry, in the wrong place.
Clipping Speed — Does It Actually Matter?
The industry sells bent gates on speed. I haven’t been able to find peer-reviewed numbers on how much faster they actually are — anecdotally, people cite differences in the tens of milliseconds, but I’ve never seen a real time-motion study. If someone at Petzl or BD has one in a drawer, I’d love to read it.
Does it matter? Depends where you are. If you’re pumped on a 35-degree overhang holding a bad crimp, the clip either goes or it doesn’t, and the bent gate’s main gift is tactile — the rope seats into the curve automatically, so you’re less likely to fumble it off the gate while your forearm is screaming. On a 5.8 slab or a top-rope, it’s basically irrelevant.
Where Bent Gates Shine
A few places they genuinely earn their spot:
- Long sport routes. Fifteen draws on a 30m pitch adds up. Smoother clips mean a slightly lower heart rate at the chains.
- Overhanging terrain. When you can’t actually see the biner, the curve guides the rope in by feel.
- Redpoint attempts. At your limit, the micro-efficiencies either stack in your favor or they don’t. This is where I notice the difference most — not because any single clip is faster, but because the whole sequence feels less fraught. You’re not thinking about the clip; you’re thinking about the next move. Over a 25-move route, that mental bandwidth is the actual product you’re buying.
- Project draws. If you’re leaving draws up for weeks on a proj, something like the Edelrid Bulletproof (51g, steel insert in the rope basket) resists the groove-wear that repeated whippers chew into aluminum. Heavy, but you’re not carrying them up anything.
Where Bent Gates Are the Wrong Tool
Bent gates are specialized for one action: shoving a lead rope into a basket under duress. Outside of that, they range from pointless to actively annoying.
| Application | Bent gate? | Why |
|---|---|---|
| Bolt end of quickdraw | No | Curve can hook the hanger during a fall. |
| Anchor masterpoints | No | You need a locker. A non-locker gives you zero security here. |
| Racking cams/nuts | No | Curve snags on gear loops; one-handed removal is a fight. |
| Personal tethers (PAS) | No | Lockers only at the belay. |
| Trad placements | No | Slings off a cam snag in the curve — straight or wire is cleaner. |
Solid Bent Gate vs. Bent Wire Gate — The Choice Nobody Explains
Three things separate a solid bent gate from a wire gate with a bent profile: weight, flutter resistance, and what happens when it’s cold.
Solid gates (Petzl Spirit, for example) use a milled aluminum bar. They feel substantial, and almost all of them come with a Keylock nose, which is what you want for sport. Wire gates (Camp Photon Wire being the obvious one) use a stainless steel loop. The wire has way less mass than a solid bar, so it resists gate flutter — that phenomenon where the impulse of a hard catch vibrates the gate open for a few milliseconds. In theory a flutter at the wrong instant could matter. In practice, I’ve never personally witnessed a flutter failure, but I’ve also never bet against physics.
Wire gates also don’t freeze shut. That’s why they’re the default on anything alpine or ice.
2025/2026 model comparison:
| Model | Gate Type | Weight | Open Gate Strength | Nose Type |
|---|---|---|---|---|
| Petzl Spirit | Solid Bent | 37g | 9kN | Keylock |
| BD HotForge | Solid Bent | 45g | 8kN | Keylock |
| DMM Alpha Sport | Solid Bent | 45g | 9kN | Keylock |
| Camp Photon Wire | Wire (bent profile) | 30g | 9kN | Notch |
I still rack dedicated Spirit draws for anything I actually care about redpointing, even though the Photon Wires are objectively lighter and the open-gate numbers are a wash. Habit, mostly. Old habit, not justified.
The Alpine Draw Question
Can you build a 60cm alpine draw with a bent gate on the rope end? Sure. Most people don’t.
The whole point of alpine draws is to kill rope drag on wandering routes, and if you’re carrying 10 to 15 of them on trad, weight wins. Dual Photon Wires save you about 30g per draw compared to dual Alpha Sports. Across 15 draws that’s close to a pound, which you’ll feel on the fourth pitch.
The exception is sport climbers who extend bolts under a roof. The sling kills the drag, and they’d rather keep the bent-gate clipping feel they already know from their regular draws. Reasonable tradeoff.
Downsides are the same as always: heavier than wires, and the curve snags on your gear loops when you’re racking.
Buying Checklist
What to actually look for when you’re picking bent gates for a quickdraw set:
- Keylock nose. Smooth, no notch. A notched nose will grab the rope while you’re cleaning a steep route and ruin your afternoon.
- Open gate strength. UIAA 121 minimum is 7kN. Most decent sport biners come in at 8 or 9. Don’t buy anything at the floor.
- Weight. 35–45g is the sport sweet spot. Push past 50g and a rack of twelve starts to pull on your harness in a way you’ll notice by pitch three.
- Basket depth. Deeper rope basket, cleaner rope seat against the spine, less cross-loading drama.
- Gate tension. Snap it with your thumb. Should return hard but open without any gritty feeling.
One more thing on the nose: if you’re buying used, run a fingernail across it. Any burr at all, pass. That burr becomes a rope snag in six months.
FAQ
Can you use a bent gate carabiner on the bolt end of a quickdraw?
No. The curve can hook the hanger during a fall and pry the gate open.
Is a bent gate safer than a straight gate?
Neither is inherently safer — they do different jobs. Straight gate is safer on the bolt because it won’t catch the hanger. Bent gate is safer on the rope because you’re less likely to fumble a clip when you’re pumped. The danger comes from putting them in the wrong position, not from the design itself. Mix them correctly on a draw (straight on the bolt, bent on the rope) and you get the benefits of both.
Do you need bent gates if you’re just starting sport climbing?
Recommended, not required.
What’s the main difference between a bent gate and a wire gate?
A solid bent gate uses an aluminum bar and usually has a Keylock nose. A wire gate uses a stainless steel loop — lighter, won’t freeze, less prone to flutter during a hard catch.
