["The set comes with 2 pulley wheels, 8 self-tapping screws and 8 expansion pipes, covering the basic hardware needed for installation. As for the size: the sheave diameter is 48mm, overall length 68mm, overall height 60mm, and each mounting hole measures 7mm.","Heavy Duty: Constructed from heavy-gauge 304 stainless steel, this pulley resists rust and corrosion, maintains its shape well, and is simple to clean. The reinforced plate design supports a maximum load of around 800 lbs (though actual capacity may vary depending on mounting angle and surface material). That makes them a solid choice for various heavy-duty traction and lifting jobs.","Easy Installation: Installing each pulley is fairly simple. Just mark the four spots, drill 10mm holes, push in the yellow expansion anchors, and fasten them with the self‑tapping screws. You won’t need any specialized tools to get the job done. The U‑shaped groove is designed to fit flat belts or round ropes between 3mm and 12mm wide, and its smooth finish helps minimize wear on the rope during use.","Dual-Bearing Design for Quiet Performance: Featuring two double-row bearings, this pulley is designed to reduce friction, resulting in smooth rotation and very little operational noise. It works well in indoor applications such as home gyms, where quieter operation is often a consideration.","Wide Application: This pulley works well in a variety of settings, including home gym pulley systems, wire rope traction, inverted tracks, sliding or rolling shutters, clotheslines, awnings, and various outdoor projects."]
