Replacement Insert for 15089 Arcadia Mortise Lock

Replacement Insert for 15089 Arcadia 700 series Mortise Lock with 45 degree keyway The plastic part is what normally breaks on this sliding patio door lock

Contents 1 nylon insert  1 spring    Installation: Looks like the way to do it is, drill out the existing plastic, do not pry the housing apart.  Then get the new part inserted, the housing itself will snap the new part in place.  The spring does not connect to anything, just goes in the hole.

NOTE: this is not intended to replace parts on other brands of locks
