LOC PRO Motor Retainer
Works really well. Used it to adapt a 38mm J270 to a 54mm LOC Wolverine.
This retainer is beautiful made. Fits perfectly and performs as good as it looks.
Loc pro retainer just like there kits well made,the best
This retainer is very tight when using the MMA-2 motor adaptor. I had to peel off the top layer of the adaptor to be able to fit it through the retainer.
