Overview

A four piece set of AC04S clamps sold together as a pack. The listing gives no material, jaw size or clamping force, so the pack count and model number are the only confirmed details available here.

Data on this listing is limited to the model number and pack count, so specifics like jaw opening, clamping pressure or body material are not available. Buyers should check the product listing images and dimensions directly before ordering if precise capacity matters for the job.
