The Icon Moveable Support Leg provides a completely adjustable solid foundation for practically any drum rack. Adaptable to Pearl's original square support rails as well as other 1.5" round rack bars its main tube houses a 7/8" telescoping bar via an included PCL100 auxiliary clamp. This is ideal for adapting added support legs to a larger rack set-up via standard accessory clamps or housing a multi-clamp for mounting added tom or cymbal arms.
