220-9095 K90 Weld-On Two-Strap LH Corner Bucket Adapter for CAT Excavators

The 220-9095 K90 Weld-On Two-Strap LH Corner Bucket Adapter is an aftermarket replacement for compatible Caterpillar excavator bucket applications. Designed for installation on the left-hand corner of the bucket cutting edge, the adapter provides a secure mounting interface for K90 bucket tips while adding protection to a high-wear area of the bucket.

Its two-strap weld-on construction distributes digging loads across the bucket base edge and provides a stable connection between the bucket and the tooth system. The corner configuration combines bucket-corner protection with the penetration benefits of a replaceable digging tip.

This adapter is designed around a 40 mm base edge with a 22.5-degree bevel. Official reference dimensions include an overall length of approximately 351 mm, a bottom strap length of approximately 223 mm and a width of approximately 99 mm.

Typical applications include excavation, construction, quarrying, trenching and general earthmoving. Before ordering, buyers should verify the part number, left-hand orientation, bucket edge thickness, bevel angle and installed tooth system. Machine model alone is not sufficient to guarantee fitment.

This is an aftermarket replacement component and is not represented as a genuine Caterpillar part.
