Frequently asked questions
What pad do these use?
A smooth PSA (sticky-back) backup pad — not hook & loop. Shop PSA Backup Pads.
PSA vs grip (hook & loop)?
PSA sticks directly to a smooth pad and runs very flat; grip discs peel on and off for quick changes. For the hook & loop version see the 6" Rhynogrip (620).
Red Line vs White Line?
Red Line is the premium, longest-life, highest-cut line; White Line is the everyday line.
Quality you can trust: made by Indasa — ISO 9001 / IQNET-certified manufacturing, backed by the Indasa Academy and 45+ years of abrasive expertise.
