But even this powerhouse depends on one small component for reliable connections: the Stabbing Guide 125158.

In this guide, we’ll explain what the Stabbing Guide 125158 is, why it’s essential for your TDS11SA, and how proper use can protect your threads, cut downtime, and keep your rig safe.

What Is the Stabbing Guide 125158?

The Stabbing Guide 125158 is a precision alignment device mounted on the TDS11SA top drive. It ensures the top drive’s output shaft (saver sub) aligns perfectly with the box end of a drill pipe joint before makeup. When you use the Stabbing Guide 125158, confirm every stab is straight, clean, and safe.

Why the Stabbing Guide 125158 Is Critical for Your TDS11SA

Without proper alignment, repeated stabbing operations can cause:

Problem Consequence

Thread damage: Connection leaks or downhole failure

Saver sub wear: Premature replacement (costly & time‑consuming)

Downtime: It’s critical, every minute counts for oil and gas industry

Safety risks: Pinch points, hand injuries from manual alignment

Premium connections require a Stabbing Guide 125158 to avoid thread galling.

How to Install & Operate Stabbing Guide 125158 – Best Practices
