A chalk reel includes a housing defining a chalk chamber and an opening from the chalk chamber; a spool positioned within the chalk chamber; and a line wound on the spool and extending through the opening, the line having a width of dimension X. The spool comprises an axial hub and a sidewall. The sidewall comprises a plurality of apertures extending through the sidewall from a first face distal from the axial hub to a second face proximal to the axial hub. Each of the plurality of apertures having a maximum width of dimension Y. The dimension Y is less than or approximately equal to twice the dimension X.

A guide assembly for a tape measuring device may include an inner guide portion facing a reel assembly of the tape measuring device, and an outer guide portion facing away from the reel assembly. The guide assembly may be configured to enable the tape to be paid out from an aperture of the tape measuring device in both lateral directions relative to the aperture.

A nozzle for a chalk box that includes a housing and a chalk reservoir may be configured to be releasably coupled with the housing. The nozzle may include a shell, and a nozzle flange assembly configured to interface with a case flange assembly of the housing to operably couple the nozzle to the housing. The nozzle flange assembly may include a locking member. A gasket portion may be integrated into the locking member to seal an interface between the nozzle flange assembly and the case flange assembly to inhibit chalk leakage from the chalk box.

A chalk reel is provided that includes a handgrip on housing supporting a chalk line extending from a nozzle of the housing that extends from the chalk reel to mark a straight line. The chalk reel may further include a rotatable handle that rotates to extend or retract (“pay out”) the chalk line. A hook is secured to the end of the chalk line to facilitate extension of the chalk line and prevent retraction of the chalk line end into the housing nozzle. The chalk reel may further include a transmission system with gearing and a selector to lock the gearing at locations around the handle rotation. The chalk reel may also include a large removable cap to facilitate refilling the chalk or other marking material.

A drive assembly for a tool with a rotatable crank and a reel may include a carrier operably coupled to the reel, a stress relief plate interposed between the carrier and the crank and configured to operably couple the carrier to the crank, and mating surfaces disposed on the carrier, the stress relief plate, and the crank in a stacked arrangement to distribute stresses and increase maximum torque capacity of the drive assembly.
