They all shrink, period! I would like to find a plastic trim piece chromed like the ones you find at Pep boys, only the right size. I may have some triangular inserts. I will look tomorrow.
A fabricated metal triangle is less pliable and more prone to damage(cut or create a tear) the recess of the pull handle. Yes, could be made slightly smaller but probably best to locate a plastic replacement.. . .The triangular inserts were missing and I can make a pair out of sheet metal, but I'm a bit concerned it it is too tight I won''t be able to remove them. Of course, make it on the loose side, but it would be nice to have a pattern.
