Sliding hammer/Bi-Puller coupling (508021)

Wielander & Schill Slide Hammer Bi-Puller Adapter (508021)

The Wielander & Schill Slide Hammer Bi-Puller Adapter is a compact coupling that connects your slide hammer to a Bi-Puller system. As a result, you can use the pulling force of a slide hammer together with the grip and control of Bi-Puller attachments. This makes it a key link in your panel repair toolkit.

Made from nickel-plated steel, this adapter is built to handle repeated heavy loads without bending or wearing out. In addition, the nickel coating protects against rust, so the coupling stays smooth and reliable even in a busy workshop.

Key Features

• Bi-Puller compatible — connects your slide hammer directly to Bi-Puller pulling systems
• Nickel-plated steel — tough, rust-resistant, and built for daily workshop use
• Compact size (64 × 46 × 36 mm) — fits into tight spaces around damaged panels
• Lightweight 190g design — adds minimal weight to your slide hammer setup
• Precision fit — locks securely to both the slide hammer and Bi-Puller attachments

How Does This Adapter Work?

A Bi-Puller system uses special clamps or hooks to grip damaged panels from the outside. However, on its own, a Bi-Puller relies on manual force. By adding this adapter, you can attach a slide hammer to the Bi-Puller. As a result, each pull delivers a sharp, controlled impact that draws the dent outward. This is much faster and more effective than pulling by hand alone.

To use it, first attach the Bi-Puller clamp or hook to the damaged area. Then, thread this adapter onto the Bi-Puller. Next, connect your slide hammer to the adapter. Finally, slide the hammer weight along the shaft to create pulling force. Because the adapter locks firmly at both ends, all the energy transfers directly into the panel.

Typical Uses

• Connecting a slide hammer to a Bi-Puller system for panel pulling
• Dent removal on body panels, doors, wings, and quarter panels
• Pulling creased or buckled metal back into shape during collision repair
• Working alongside clamps, hooks, and other Bi-Puller attachments
• General bodyshop straightening tasks that need controlled pulling force

Why Nickel Plating?

Nickel plating gives the steel a hard, smooth surface layer. As a result, the adapter resists rust and wear far better than bare or painted steel. Furthermore, the smooth finish means the coupling slides on and off cleanly, with no snagging or sticking. This matters when you need to swap tools quickly during a busy repair job.
