4” Cable Pulley
4-inch cable pulley constructed to a 1.8mm steel thickness specification — heavier than the standard 1.2mm pulley series — providing additional wheel body rigidity for high-cycle or heavier residential door applications. The increased material thickness reduces flex in the pulley body under dynamic cable loads, maintaining consistent groove geometry through extended service. The 4-inch diameter keeps cable bend angles shallow, reducing cable wear and extending cable replacement intervals. Suitable for use in the cable routing position on torsion spring residential sectional door systems where a heavier-duty pulley wheel is specified.
