The present invention relates to a protective spool dispenser that is portable, efficient and convenient for dispensing line. The dispenser has four corner members and upper and lower sidebars, forming a box-like outer frame. A crossbar extends between two adjacent corner members. A spool-receiving arm extends from the crossbar. The end of the spool-receiving arm opposite the crossbar is unsecured, so that a spool of line may be easily slid onto the arm. The arm includes a tensioning spring, two washers and a fastening pin. The spool is sandwiched between the two washers. Free spinning is prevented due to the tensioning spring. The disclosed dispenser also preferably includes a cutter mechanism for cutting line to desired lengths.
