Abstract
Provided is a caliper extender (100), which fits over a tape measure blade (124), enabling accurate measurements to be taken of an inside dimension (142). Extender (100) slides along blade (124) and is positioned against one wall of the inside dimension (142). Blade (124) is then repositioned flat against extender (100) and a measurement reading is taken. A pointer (110) may also be incorporated into extender (100) to indicate a tape marking (202, 204, 206, 208 or 210) corresponding to an accurate measurement. In the alternative, a caliper extender (160) is incorporated into a tape measure (350) such that extender (160) can be disengaged from a casing (352) of tape measure (350), slid along a blade (190) and a measurement reading taken through a window (308) in a channel (304) through which blade (190) is installed.
