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.
Well made piece. They have annular grooves in the piece that attaches to the engine mount tube to give the epoxy a good grip. A little less engagement than other brands but I think the grooves make it a better grip.
I bought LOC products from Ron and Deb Shultz. The new owner is doing great.
