WEHA Backup Pad – 5 in., Aluminum, Rigid, Hook & Loop, 5/8 in.-11 Thread
The WEHA Backup Pad is a 5 in. rigid aluminum backup pad with a hook-and-loop face, used to hold 5 in. hook-and-loop polishing pads on a polisher. The aluminum body is rigid rather than flexible, so it holds the abrasive flat against a surface instead of letting it roll over an edge.
A rigid backer is what a fabricator uses for flat surface work — blending a repair across a top, or running a surface polish where any flex would leave a wave. Curved profiles and sink bowls need a flexible backer instead.
Key Features
- 5 in. diameter aluminum body
- Rigid, for flat surface work
- Hook-and-loop face for 5 in. hook-and-loop pads
- Aluminum construction dissipates heat better than a plastic backer
Who Is This For?
Fabricators and repair technicians running 5 in. surface pads flat on a top. It is not the pad for the WEHA 3.5 in. Turbo Polishing Discs — those are rigid discs that need the matched 3.5 in. backup pad with the interior anti-shift ridge (WEH 51080). For curved edge profiles, use a flexible backer such as the Alpha Flexible Backer Pad, 5 in. (ALP GP55/8PD).
Frequently Asked Questions
What size pads does this backer hold?
It is a 5 in. backup pad with a hook-and-loop face, so it holds 5 in. hook-and-loop polishing pads.
What is the difference between a rigid and a flexible backer?
A rigid backer holds the pad flat and is used for surface work; a flexible backer lets the pad conform to a curved edge profile such as a bullnose or an ogee.
Can I mount the 3.5 in. Turbo Polishing Discs on it?
No. The WEHA 3.5 in. Turbo Polishing Discs mount on the 3.5 in. backup pad, WEH 51080, which has an interior ridge that stops the disc shifting.
Why aluminum instead of plastic?
An aluminum body is rigid and carries heat away from the pad, which matters on long surface-polishing passes.
