PUK vertical ladders are the ideal solution for routing cables and lines vertically. Typical areas of application include vertical ducts in buildings or industrial halls. The vertical ladders can be quickly and easily mounted directly on the wall or installed free-standing (STU 60/62 as well as ST 81/82) using head and foot plates, brackets or corresponding mounting accessories. The product’s strength is the way it allows cables to be attached securely in conjunction with PUK cable clamps. The standard range includes vertical ladders in light, medium and heavy-duty designs. For truly effective cable routing, our heavy-duty vertical ladders enable you to attach cables on both sides. The system is available with perforated side rails with L, U or I profiles.
