At iStudio Projects, our IWEISS Black Single Carrier (Part # IWI28) is a high-performance I-Beam Curtain Track carrier engineered to deliver smooth, quiet, and reliable curtain travel in both straight and curved track applications. Built with a pair of nylon wheels featuring shielded ball bearings and rivet attachment, housed within a zinced black formed steel body, the IWI28 is designed to handle heavier loads than standard carriers while minimizing noise and friction through integrated plastic glide strips in the housing. Compatible with 3/16″ or 1/4″ rope, the carrier suits bi-part and one-way draw systems as well as walk/draw operation, and features a swivel hook and trim chain for flexible, twist-free curtain attachment. Compact at just 1-1/4″w x 5-1/8″h and weighing only 2.7 oz, the IWI28 is rated at 8 lbs per carrier on 12″ spacing — making it an ideal choice for professional stage curtain systems requiring both performance and versatility across straight and curved track layouts.
