The DHOT Impression Block is an accessory tool used to accurately determine the dimensions and configuration of the upper end of a fish as well as to check its condition and position in the well bore.
The soft lead lower end of the impression block captures an impression of the fish upon making contact. Impression blocks are manufactured with a pin or box up connection and a layer of soft lead on the lower end of the tool.
Impression blocks are manufactured from 4140HT or 4145M material.
