Product Description

  • All models are machine from hardened steel to make a very sturdy and lasting tool.
  • We use double lead fast threads instead of ACME threads because they are as fast, if not faster, to screw on and more importantly, we have found that ACME threads tend to loosen, and don’t hold job as secure as our double lead fast threads.
  • Models 42050-TM, 42050-T and 42050-TL have one pin that has a 360° vial for easier vertical leveling that just “snap” in and out for easy replacement.
  • The 42050-TXL model fits flanges with hole sizes to 2-7/8″ in diameter.

*Level not included


See the Flange Hole Diameter Reference Chart to check hole diameters for your specific flange.

Extensions available for threaded models to accommodate thicker flanges:

  • 2-7/8” Stud #0501
  • 4-1/2” Stud #0503
  • Coupling #0503-EX
