Claims20
A pipe guide comprising
- a base,
- base extension apparatus having a first end and a second end, the first end pivotably secured to the base, the base extension apparatus selectively extendable in length from the base,
- holder extension apparatus selectively extendable in length and having a primary end and a secondary end, the primary end pivotably secured to the base, the second end of the base extension apparatus pivotably connected to the holder extension apparatus so that extension of the base extension apparatus pivots the holder extension apparatus with respect to the base, and
- pipe holder apparatus pivotably connected to the secondary end of the holder extension apparatus.
