At iStudio Projects, our IWEISS Channel Track Black Single Carrier (Part # IWC18) is a heavy-duty curtain carrier engineered for smooth, reliable performance in straight Channel Curtain Track systems. Built with two Performance Thermal Plastic Rubber (TPR) wheels featuring shielded ball bearings and rivet attachment, housed in a durable black nylon body, the IWC18 is designed to handle heavier loads than standard carriers — rated at 20 lbs per carrier on 12″ spacing. Compatible with 3/16″ through 1/2″ rope, this carrier is suitable for bi-part and one-way draw systems as well as walk/draw operation. A swivel hook and 6″ trim chain provide flexible, twist-free curtain attachment with adjustable drop height. Compact at 2″w x 11-1/2″h and weighing just 7.8 oz, the IWC18 delivers high load capacity and quiet, dependable curtain travel for professional stage installations.
