ABSTRACT:
A marker attachment for an elongated rule, such as a metal measuring tape adapted to be stored in compact coiled condition in a case from which it is extendible and into which it is retractable. The marker attachment has at least one integrally formed projection with a pencil-point receiving hole therein. Preferably, the attachment is integrally formed from flexible, but relatively stiff, plastic sheet material and in use slideably embraces a rule or tape. Also, it is preferred for the attachment to have an integral pointer which is aligned with the pencil-point receiving hole in a direction transverse to the rule and registrable with rule markings. In addition, it is preferred to provide the attachment with a piece of friction material which will engage the rule and tend to retain the attachment in place when moved to a desired position on the rule.
