Abstract: A plug (1) for use with a counterbalancing system (3) of a cable-operated door (5). The plug (1) includes flange and collar portions (13,15), the flange portion (13) being connectable to a mounting component (7) of the counterbalancing system (3) in order to allow a torque transfer from a torsion spring (9) to the mounting component (7), and the collar portion (15) being configured for winding into a given end (17) of the torsion spring (9), the collar portion (15) having opposite first and second extremities (19,21), and an outer surface (23) extending between these extremities (19,21), the outer surface (23) of the collar portion (15) being provided with a plurality of threads (25) and a plurality of corresponding recesses (27) each being defined between a pair of adjacent threads (25), each recess (27) being configured for receiving therein a single coil segment (11a) of the torsion spring (9), and being further shaped and sized for preventing another coil segment (11b) of the torsion spring (9) from embarking onto said recess (27).

Abstract: A tensioning assembly for winding a winding system includes a support bracket connectable to a fixed frame, a collar portion removably mountable onto a shaft of the winding system proximate to the support bracket, a ratchet wheel, and a pawl component. The collar portion is removably secured onto the shaft. The ratchet wheel is securely mounted onto the collar portion and is rotatable therewith. The ratchet wheel has a plurality of teeth and a plurality of corresponding recesses. The pawl component is operatively mountable on the support bracket and is moveable with respect to said support bracket, the pawl component having an extremity being positioned, shaped and sized with respect to at least one recess of the ratchet wheel for allowing rotation of the shaft along a winding direction, and for blocking rotation of the shaft along an unwinding direction.
