  • Construction string reel
    Patent number: 4662078
    Abstract: Disclosed herewith is an improved reel assembly for surveyors and other construction trades wherein the resilient member that retrieves the plumb line or string is entirely enclosed in the spool assembly that is contained within the housing of the reel assembly. The spool assembly is formed so that it is difficult to obtain access to the resilient member thereby precluding inadvertent release of the spring assembly.
