Remarks: 
Overshot Tubing Seal Divider This equipment is usually recommended for use in wells where sand or trash present a problem in retrieving wireline plugs. The inner mandrel incorporates an integral nipple profile where a plug can be installed. The divider overshot is run on the tubing and latched on the divider mandrel, protecting the plug choke from trash, sand, and debris. A simple turn of the tubing (at the divider) is designed to release divider mandrel.
