Items equipped with e-port (electronic firing ports) contain a plastic firing port which will accept standard e-match or Firewire Initiators. The e-port is typically located on the tube of the last shot of nearly all '76 ProLine cakes. The location is marked with either a '76 ProLine logo or e-port logo. Firing '76 ProLine cakes in reverse does not affect performance because they are typically solid effects and contain consistent fusing with no finale row.

Twist Lock Ports
Items equipped with t-lock (twist lock ports) contain a plastic firing port which has a twist lock feature that mates with FS143 Firewire Initiator with t-lock Shroud. The FS143 twist lock shroud allows operators to quickly prep product without any special tools or tape. These ports will also work with standard e-match or firewire.
​
Unless marked for Professional Use Only, all '76 ProLine items are equipped with a standard visco fuse for hand lighting or electronic ignition with Talon / Safety Clip Ignitors. Professional Use Only items do not typically contain any external fuse. These items are designed to be fired electronically by a professional using e-match or Firewire Initiators only.
