1600A01CU1 supersedes older part numbers: 2609100541

Original Bosch 1600A01CU1 — Hook‑and‑Loop Rubber Backing Pad (127 mm diameter). Direct replacement backing pad designed for 127 mm (5") hook‑and‑loop sanding discs, with eight dust‑collection holes that line up with the tool’s vacuum port for cleaner sanding and longer abrasive life. Genuine Bosch part; replaces Bosch legacy part number 2609100541 and is matched to the mounting pattern and screw locations used on Bosch ROS palm‑grip random‑orbit sanders.

Fits common Bosch models such as ROS10 and the ROS20VS / ROS20VSK series (check your machine’s model plate to confirm). This backing pad snaps/screws into place the same way as the original, restoring proper abrasive retention and dust extraction so you can get back to work quickly when you need parts for power tools.

What you get: one genuine Bosch 1600A01CU1 hook‑and‑loop rubber backing pad (127 mm diameter, 8 vacuum holes) that mounts directly to the ROS10 / ROS20VS family of sanders and replaces part 2609100541.
