EG25 Wire Pull (10-Pack)
Burn: 25 seconds per unit. Format: compact, sold as 10-pack only. Ignition: wire pull from side ring. Use case: volume for teams, group pulls, or budget testing before upgrading to WP40-D.
WP40-D Wire Pull
Burn: 60 seconds. Vents: single directional outlet. Ignition: wire pull. In stock. Default spec for photography and outdoor events when you need sustained output at the lowest in-stock single price.
TP40 Top Pull
Burn: 60 seconds (same sustained class as WP40-D). Vents: single. Ignition: top pull (ring upward from cap). In stock. Choose TP40 when glove-friendly or one-handed activation matters more than lower price on WP40-D.
Twin Vent II Wire Pull
