A power actuated tool (20) for driving a fastener into a substrate such as steel or concrete, comprises a housing (2), a barrel assembly (5) mounted to the housing, and a piston displaceable within the barrel assembly upon firing of the tool to drive a fastener from the forward end (25) of the barrel into the substrate, at least a forward end of the barrel assembly being mounted for axial movement relative to the housing whereby firing of the tool requires the forward end (25) of the barrel assembly to be pressed against the substrate to cause retraction of the forward end relative to the tool housing. A telescope shroud (21) surrounds the forward end of the barrel assembly to at least partially suppress noise emission resulting from firing of the tool.
A shroud for use with a power actuated tool for firing a fastener into a substrate, the shroud being adapted to always couple between a main barrel and a slidable front barrel of the tool and being adapted to extend from a collapsed condition when a mouth of the front barrel is positioned adjacent to a substrate into which a fastener is to be fired and an extended condition when the main barrel is in a recoiled position relative to the front barrel after firing the tool, wherein the shroud defines a cavity to at least partially contain noise emission from the main barrel resulting from firing of the tool;
