The Vertical Hangers come in three lengths (150cm, 300cm and 500cm) with two finishes (clear translucent or silver steel).
For most situations the 150cm length of hangers will be more than long enough.
If you have installed the rail at the top of a high ceiling, you may need the 300cm lengths. Occasionally, tall commercial spaces may need the 500cm vertical hangers.
TIP: If the Vertical Hanger can be seen below the picture you are hanging, roll up any unused length and hide it behind the back of the picture using some tape.
