Product Description

Product Description

TIANHE Series 150 Releasing and Circulating Overshot can be equipped with a wide range of accessories  to meet a variety

of complex fishing environmental.

Extension Sub
An extension sub is assembled between the top sub and the bowl. It is used when the upper portion of the fish is damaged or cannot be engaged. This accessory will permit the overshot to be lowered far enough over the fish to ensure secure engagement and pack off. They are available in lengths from 24 to 60 inches. When ordering, specify overshot O.D. Unless otherwise specified Extension Subs will be furnished in a standard 36-inch length.

Wall Hook Guide
If the fish is positioned in a washed out section of the hole, it  may be difficult to engage the top of the fish using a conventional overshot guide. A wall hook guide can be used to capture the neck of the fish, centralize it, and then properly guide the fish into the bowl

Oversize Guide
Oversized Guide properly guides the fish into the overshot when the hole size is considerably larger than the diameter of the fish  and the overshot may pass alongside the fish without engaging it. Installation of an oversized guide instead of a standard guide will ensure alignment of the fish with the overshot.

Mill Extension
Overshot Mill Extension interiors are faced with lncoloy to a size that will mill away a flared or jagged fish to enable it to pass up into and be engaged by the Grapple in the Bowl. Mill Extensions are installed between the Bowl and the standard, oversize or wall hook guides.


Mill Guide
Overshot Mill Guides are designed to remove badly flared or jagged metal from the top of the fish. Mill Guides are used in place of the Standard or Oversized Guide to trim the fish so it can enter the overshot
