"The [Winchester] Ringblaster® Industrial tool is a heavy-duty shooting apparatus that is designed for multiple industrial applications. The industrial tool is coupled with our specialized Ringblaster® Mount system which has a precision weight balanced construction that helps maintain bull’s-eye accuracy, with substantially reduced vibration and recoil. The Ringblaster® can be fired by a manual lanyard operation or an auto fire operation. The Ringblaster® has been used by the cement, lime, and ferro alloy industries for over 60 years. Because it has proven to be durable, versatile and cost effective, it has been the tool that these industries depend on.
The Western™ Industrial Tool is a portable alternative to the Ringblaster®. This tool utilizes a pistol grip and hanging bracket to allow an operator to shoot and maneuver in much tighter spaces and from a more broad range of angles. It was originally designed to remove ash build-up in power plant boilers. The portability and versatility of the Western™ tool makes it useful for many other industrial applications."
