A key component of the tooth system – a high-quality Casting Forged weld-on adapter (tooth holder), compatible with the popular Bofors B-Lock system, size B1. This is a precision casting designed to be welded onto the cutting edge of a loader (Clamshell) or excavator bucket. It creates a durable socket (or "nose") for Bofors B1 teeth (tips), allowing for quick and secure replacement using a vertical lock pin.

Welding an adapter is a critical operation. Proper pre-heating of the adapter and bucket lip must be observed to avoid weld cracks. When installing/removing teeth (knocking out pins 6254675), always wear safety glasses. Metal fragments can fly off and cause serious eye injury.
The adapter is the foundation of the tooth system. It is permanently joined to the bucket and transfers all digging forces from the lip to the replaceable tooth. Its "nose" is the key locking component that must remain in perfect condition to prevent tooth loss.
