Long Duration Gerbs
Plumes of silver or gold sparks of varying height and duration, shoot up to create a glittering effect.
The first number shows the burn time (in seconds) and the second number shows the height (in feet). The height is defined as the top of the main plume, some sparks will go higher. For example: a 3 x 20 is a gerb of 3 seconds duration that reaches a height of 20ft.
Please note that the red caps are no longer fitted or supplied with our Stage Gerbs. If required, these can be sent out at no additional charge AT THE TIME OF PLACING THE ORDER. However, should these red caps be needed without the Stage Gerbs, they are available to purchase.
