A nailer is provided for securing planks to a subfloor in tight places with fasteners. A fastener ejection channel made in the nailer is formed in between a pair of first and second guide plates spacedly mounted parallel to one another. The first guide plate defines a planar inner end portion having an ovoidal slot and an outer end portion defining a transverse arcuate first flange. The second guide plate defines an arcuate second flange extending away from the first guide plate and generally parallel to the first flange. An elongated straight push rod is mounted partially nested at an inner end in the ovoidal slot. The bottom portion of the push rod is movable along the fastener ejection channel between first and second limit positions. A lengthwise notch extends along the second guide plate intermediate section and opens into the second flange and is sized and shaped to accommodate transverse passage of an outer end portion of the push rod, wherein the push rod moves rectilinearly between the first and an intermediate position thereof but the push rod outer end portion tilts laterally away from the first guide plate when moving in non-rectilinear fashion between the intermediate and second limit positions thereof.
