Stair Units

Universal System Scaffold easily adapts to the requirements of complete stair units. Standard components combined with minimal stair-related parts as illustrated below and on pages 9 and 10 permit simple assembly of these units:

1. Assemble base section as shown.
2. Attach USSL70 Stair Stringers to upper and lower UH40 Horizontal.
3. The UST30 Stair Treads are inserted with a "rotary motion" into their respective channel supports.
4. Required hand rail consists of four (4) UD70 Diagonals assembled in the two (2) rosettes just
   above the stair base.
