Our Hollow Guide Rail TK3 TK5 are high-performance elevator components designed with a rectangular hollow section and flat edges (non-flanged). These guide rails are specifically tailored for TK Elevator systems and are widely used in machine room-less (MRL), residential, and commercial elevators. Compared to traditional solid or flanged guide rails, the hollow + flat-edge design delivers a lighter structure, easier installation, and precise compatibility with elevator cars and counterweights in TK-branded systems.
