Abstract
A marker is provided for attachment to a pipe or other vessel which periodically requires inspection for wall thickness at a specified, defined position. The marker has minimum surface contact with the pipe to protect against moisture accumulation between them. The marker is attached to the pipe or vessel by an attaching cable which also has reduced or minimum surface contact with the pipe. The marker is provided with a lock mechanism and a protective cover to protect the test area from contact by cleaning substances such as sand during sandblasting, as well as coatings or paints applied after cleaning.
