Chinook Mast Extension Pin and Leash Collar - RDM
- Mast Extension Adjusting Collar
- Circa 1996 - 2014
Note: on most older Chinook RDM extensions you can replace this old style collar with the newer snap collar. You will not be able to use the highest and lowest position on your extension, but the new collar is easier to use and with the included top cap retrofitted it's hard to lose parts.
