Wire pull and top pull are two ignition styles on the same 60-second Enola Gaye medium-format grenade. This guide compares the in-stock WP40-D Wire Pull and TP40 Top Pull - same burn time, same nine colors, different ring motion. This is not a comparison with Twin Vent II (dual-vent 25s burst) or EG25 (25s mini). For the full lineup, see the smoke grenade comparison guide.
Same Smoke Output, Different Pull
Per Enola Gaye, both the WP40-D and TP40 are medium-format grenades rated at 60 seconds of burn with a single vent. Shutter Bombs sells both in all nine colors. Your decision is entirely about which ignition motion fits your hands, gloves, and shooting workflow - not about cloud size or duration.
How Wire Pull Works (WP40-D)
Grip the canister in one hand. Hook a finger through the wire loop at the base and pull straight outward in one decisive motion. Smoke begins within 1-3 seconds. Most first-time users find wire pull intuitive because the motion mirrors pulling a pin sideways.
- Lowest in-stock price
- Familiar side-pull motion
- Works well with two hands free before the shot
How Top Pull Works (TP40)
Grip the body firmly. Pull the ring tab upward from the cap. Same 60-second single-vent output. The upward pull is easier to hit with thick gloves or when you need your other hand on a camera remote - you are not fighting a wire loop with padded fingers.
- Top-cap ring - easier with gloves
- Natural one-handed activation for many shooters
- Same 60s burn as WP40-D per Enola Gaye specs

Who Should Buy Which
Choose WP40-D if:
- You want the lowest price per grenade
- Wire pull feels natural to you
- You have both hands free at ignition (assistant or tripod setup)
- This is your first smoke bomb purchase
Choose TP40 if:
- You shoot solo and need one hand on the camera
- You wear tactical or winter gloves on set
- Upward cap pull is easier for your grip strength or mobility
- You already use top-pull grenades and prefer the motion
Pro tip: Buy one of each before a big client shoot. A five-minute test in an open parking lot tells you more than any spec sheet.
What This Guide Is Not Comparing
Do not use this page to choose between TP40 and Twin Vent II. Twin Vent II is a dual-vent wire-pull grenade with a 25-second burst - built for instant width, not 60-second sustained posing. For 90-second options, compare the Gender Reveal WP40 (pink/blue, in stock) or the standard WP40 (nine colors, currently OOS) on the full model comparison. WP40-D and TP40 are both 60-second sustained singles.

Frequently Asked Questions
Do wire pull and top pull produce the same amount of smoke?
Yes. Both WP40-D and TP40 are Enola Gaye medium-format single-vent grenades rated at 60 seconds. Ignition style does not change output volume or burn duration.
Is the TP40 the same as Twin Vent II?
No. TP40 = 60s, single vent, top pull. Twin Vent II = 25s, dual vents, wire pull. Completely different products.
Which is better for wedding photography?
Either works. Most wedding photographers default to WP40-D for price and familiarity. Choose TP40 if you are shooting solo and need glove-friendly top-pull activation. See wedding smoke bombs.
Can I mix wire pull and top pull in one session?
Yes. Color and burn time match across both models. Assign wire pulls to an assistant and top pulls to the photographer, or standardize on one style - your call.
What about the 90-second WP40 wire pull?
The classic WP40 (90s wire pull) is a separate SKU and is currently out of stock at Shutter Bombs. For 90 seconds in stock today, see the Gender Reveal WP40 or wait for WP40 restock notifications.
