The Rebco ROTRN Lock Mandrel is closely related to the ROTR, but features chamfered Keys. When a Bottom Sub is added to the assembly, it converts to a No-Go Lock Mandrel, making it suitable for applications requiring a positive mechanical stop at the nipple. It is designed to land in a ROTRN Landing Nipple of the same size and shares the identical size range of 1.500" through 4.813" with the ROTR series.

Like the ROTR, the ROTRN is available in three product code configurations: the standard Product Code 10 for sizes 1.500" through 2.875"; the Product Code 17 Interference Hold Down version for 1.781" through 2.875", which provides a positive latching structure minimizing the risk of the lock inadvertently releasing due to vibration at high flow rates; and the Product Code 18 Safety Spring version for 3.437" through 4.813", where the Shear Pin is pre-installed prior to running and lodges between the Expander Sleeve and Key Retainer once the lock is set. All assembly numbers, running tools, and pulling tools in the ROTRN series mirror those of the ROTR series. All sizes are available in a variety of materials suitable for downhole conditions.

How to Order: Product Code 10 (standard), 17 (Interference Hold Down), or 18 (Safety Spring). Specify the nipple seal bore size, material, service conditions, and whether a Bottom Sub is required for the No-Go configuration.
