T20 Grid Couplings (Type-V)
T20 grid coupling is designed to operate in vertical position without any modification.
The hubs and grids of T20 and T10 grid couplings are the same, whereas the covers are not interchangeable.
Engineers may also be interested in T10 Grid Couplings for horizontal applications. More information can be found on the below link:
