  • Patent number: 11192226
    Abstract: A carrier with a fastener depth limiter. The carrier may be used to drive fasteners of a staple type. Carriers may include a fastener holder and a fastener depth limiter securable to the holder. The holder may include an axial body with distal and proximal ends, a fastener-receiving opening in the distal end normal to the axis, and an anvil-receiving opening in which an anvil repeatedly strikes a fastener held by the holder as the holder retracts during fastener driving. The fastener depth limiter may be a collar and the collar may be axially adjustable along the holder to enable user selection of the depth limitation. A workpiece-contacting distal end of a collar-type depth limiter may be spaced axially outward from the distal end of the holder a distance approximately the same as a thickness dimension of the fastener, which may be the thickness dimension of the crown of a staple-type fastener.
