Wire Pull vs Top Pull Smoke Grenades: Which Should You Choose?
One of the most common questions we get: "What's the difference between wire pull and top pull smoke grenades?" If you're trying to decide which type is right for your shoot, event, or project, here's everything you need to know.
What Is a Wire Pull Smoke Grenade?
Wire pull smoke grenades are activated by pulling a metal ring attached to a friction wire inside the grenade. Think of it like pulling a pin — grab the ring, give it a firm tug, and the smoke starts flowing within 1-2 seconds.
Wire pull is the most common activation method for consumer smoke grenades. It's intuitive, reliable, and requires no tools or special technique.
Our wire pull products:
- THE STARTER — EG25 (~$12, 25 seconds)
- THE PULLER — WP40D (~$16, 60 seconds)
- THE BEAST — Twin Vent II (~$18, 30 seconds dual-vent)
What Is a Top Pull Smoke Grenade?
Top pull smoke grenades are activated by removing a cap or cover from the top of the grenade. Pull the top off, and the smoke begins. It's a slightly different motion than wire pull — more like uncapping a bottle than pulling a pin.
Our top pull product:
- THE MARATHON — TP40 (~$20, 90 seconds)
Key Differences
Activation Feel
Wire pull: Requires a firm, quick tug on the ring. There's a satisfying click when the friction wire ignites. Very tactile and dramatic — great when you want the "pulling the pin" visual in photos or video.
Top pull: A smooth, easy pull-off motion. Less dramatic in appearance but slightly easier to activate, especially if your hands are cold, wet, or you're wearing gloves.
Smoke Duration
This isn't really a wire-pull-vs-top-pull difference — it's product-specific. But here's how they compare:
- EG25 (wire pull): ~25 seconds
- WP40D (wire pull): ~60 seconds
- Twin Vent II (wire pull): ~30 seconds (massive output)
- TP40 (top pull): ~90 seconds (longest duration)
The TP40 happens to be top pull AND the longest-burning option, which makes it ideal for extended video takes where you don't want to fumble with a wire pull mid-shot.
Holding Position
Wire pull: The ring and wire are on the top, so you typically hold the grenade in one hand and pull with the other. After activation, you hold it by the body.
Top pull: You grip the body and pull the cap off the top. The resulting hold position is very natural — like holding a can — which some people find more comfortable for extended use.
Which Should You Choose?
Choose Wire Pull If:
- You want the classic "pulling the pin" look for photos
- You're doing a quick, punchy shoot (25-60 seconds is plenty)
- You want maximum smoke output in a short burst (Twin Vent II)
- You're on a tighter budget (EG25 starts at ~$12)
- It's your first time — wire pull is the most familiar format
Choose Top Pull If:
- You need the longest possible burn time (90 seconds)
- You're filming video and need sustained, uninterrupted smoke
- You want the easiest possible activation
- Your talent will be holding the grenade for an extended period
- You're doing multiple takes and need reliability over many uses
Can You Mix Both Types?
Absolutely — and we recommend it. Many professional shoots use a combination:
- Start with a Twin Vent II (wire pull) for the dramatic hero shot with massive smoke output
- Switch to a TP40 (top pull) for sustained atmospheric shots
- Use EG25s (wire pull) as accent pieces for subtle pops of color
Mixing types gives you the most creative flexibility on set.
The Bottom Line
Both wire pull and top pull smoke grenades produce the same high-quality colored smoke. The difference is in activation method, burn time, and handling feel. For most people, wire pull (especially the WP40D) is the go-to choice. For video production and long takes, top pull (TP40) is hard to beat.
