ShineMate Backing Plate Designed for the EX620

A super durable backing plate without going full aluminium. 

This is Shinemate's answer to increasing power transfer from pad to panel without going full aluminium. The heavy-duty power plate uses the same designs from the Shinemate Dust Devil plates with great multi-hole ventilation, an air gap between the hollow top and bottom housing with increased stiffness and no flex. You can expect a 3-8% increase in power transfer.

Standard M8 female thread will fit the majority of 5~6" long-throw polishers such as the Rupes LHR21III, Shinemate, Maxshine, Adam's swirl killers etc.
Comes with a M8 male mounting bolt.
Designed for the EX620 21mm
