Autoblock 128 – 59 mm Self-Locking Pull Clamp
The Autoblock 128 is a professional-grade 59 mm self-locking pull clamp engineered for fast, secure anchoring during structural and frame pulls. Its integrated self-locking design helps maintain stable panel engagement while reducing setup time in demanding collision repair environments.
Built from high-grade steel and rated for 6-ton pulling capacity, the Autoblock 128 is designed to deliver reliable holding power, repeatable performance, and long-term durability in professional frame straightening and heavy pulling applications.
Engineered for Heavy Structural Pulls
A threaded pin integrated directly into the pull ring allows for rapid engagement and controlled clamping force. Once secured, the clamp maintains a dependable hold that helps reduce slippage and repositioning during structural pulls.
The 59 mm jaw profile distributes force evenly across the work area, making this clamp a dependable solution for technicians who need strong anchoring performance with efficient setup and serviceability.

Why Clamp Design Matters for Safety in Modern Repairs
Vehicle construction has changed dramatically over the past several decades — with high-strength steels, ultra-high-strength steels, and multi-layered structural components now standard in modern repairs. However, many clamp designs still in circulation today were developed decades ago and have not evolved to match these materials.
In real-world use, outdated clamp designs can introduce serious risk — including inconsistent bite, slippage under load, or sudden release during pulling operations. These issues are not just performance limitations — they are safety concerns for both the technician and the repair outcome.
The Stanzani Autoblock 128 is engineered with a modern self-locking design that delivers controlled engagement, consistent clamping force, and predictable performance under load — helping reduce risk during structural pulls.
In many shops, older clamp styles are used less frequently — not because they lack strength, but because they lack predictability and confidence under load. Modern self-locking systems are designed to be used daily, not left on the wall.
