Ty-Wrap Retainer Ring? Part 2

I could see where ty-wraps could be used to hold the engine hook in place.
I'd never use masking tape again and now use black electrical tape.
Electrical tape can get gummy and could loosen up.

I found some narrow ty-wraps that were long enough to get around the engine mount tube.







Here's the engine hook with one ty-wrap in place.
Don't over tighten, you could bend the tube.

The wrap is too narrow and the engine hook can slip to the side.
Most Mylar retention rings are 1/4" wide.

Two ty-wraps side by side prevent the engine hook fro side to side movement.

You probably couldn't use a ty-wrap on a 18mm mount in a BT-50 tube, there just isn't enough room between the tubes.
The 18mm mount would be fine on a BT-55 or 60 size tube.
