SPACE FIRE/PLATE NAILING OPTION:
Space fire or plate nailing tool assemblies are devices used to staple sheathing to the plates while the panel stapler bridge is moving down the wall in an automatic operation, in conjunction with the auto return feature.  The space fire tools are activated by a switch on the control box of the panel stapler bridge, firing off a cam at 3' centers standard.
