Hello.
t appears I have made an error. My intent was to order a like-for-like replacement of two "Truth 31761" tandem rollers.However, the 81-018 that I received - while they do fit the mortise opening - are too shallow, and therefore, put the height adjusting screw below the door's access hole, and below the bottom stop.

What is the correct, Truth 31761 replacement.

Could you show me a picture of the original roller out of the door? That will help us determine if your roller is still available.
