At iStudio Projects, our IWEISS Adjustable Floor Block (Part # IWC08) is a precision-engineered floor-mounted pulley block designed for use in Channel Curtain Track assemblies. Built around a 4″ diameter nylon sheave with sealed ball bearings housed in a durable 14-gauge steel body, this floor block delivers smooth, reliable rope guidance for both straight and curved track configurations. Suitable for bi-part or one-way draw applications using 3/8″ rope, the Adjustable Floor Block features a 9″ vertical adjustment range, allowing installers to achieve precise rope alignment regardless of floor-to-track height variations. Compact, robust, and easy to install, it is an essential component for any professional stage curtain track system.
