Abstract: The telescopic measuring device is a tool that enables a user to measure distances that might otherwise be beyond their reach. A measuring blade contained within a housing may be extended until a wear block at one end of the telescopic measuring device and an end hook at the other and of the telescopic measuring device span the distance to be measured. The measuring blade may then be locked into position using a clocking clamp and the measured distance may be read through a sighting window where a sight line will align with measurement indicia on the measuring blade.
