Adapter of EMS-US/UM

All the adapters of EMS series are common to use.
You can add 2-inch sleeve on EMS-UM, and you can use the 31.7mm(1-1/4 inch)AD of EMS-UM/US on EMS-UL.
Of course, EMS-UL includes the 31.7 to 50.8AD and you do not necessarily use the EMS-UM adapter, but if you want the low-profiled 31.7mm adapter, it is a good choice.
This adapter consists of two parts, one is the bottom 2-inch cap and the other is 31.7mm AD. You can even set the BORG’s Helicoid-S on the bottom cap.
