A 50m & 25m heavy-duty extension reel is a portable power solution designed for long-reach applications, featuring 50 meters of 3-core cable (typically 2.5mm thickness) on a durable PVC or steel reel. Ideal for construction, workshops, and landscaping, these reels usually feature 3–4, 13A-16A sockets with safety features like built-in overload protection, a 220–240V rating, and a winding handle for easy cable management.
