Rail ends attach to rails on one end and have a flange on the other end to attach to floors, walls, and ceilings.

Anodized aluminum resists corrosion and wear better than uncoated aluminum and has a finished appearance.

Black powder-coated aluminum blends in with backgrounds and hides dirt and grime.

Adjustable-angle fittings can be positioned at any angle. Tighten the set screw to secure.
