ABSTRACT:
A tube slide includes a combination of common curved and straight tube bed sections connected through a radially extending flange where the lowermost tube section is curved and may be rotated in either direction to accommodate space limitations. A contoured apron open from above having a protective handrail and a radially extending arcuate end flange on its upper end adjustably connected to the end flange of the lower end of the slide provides for safe exiting from the slide.
