WHY USE A TELESCOPIC STEM?

Telescopic stems eliminate the need for precise field measurement usually required for fitting extension stems. They also provide for ground movement caused by freezing and thawing.

Here's how to order:

  1. Specify direction of open (open left or open right)
  2. Model required (available in 57, 275 or 870 turns)
  3. Extension stem required (telescopic)
    1. Length required (provide “A” dimension on the illustration shown HERE)
    2. Carbon steel or stainless steel
  4. Debris Shield Item #367-9415 recommended for buried service
