The 2GBM drawing also identifies 14.50mm cover sections, an 8.10mm lower mounting section and a 4.90mm end detail. The common square-pin reference is 1mm. Use the model-specific outline for mounting and retention geometry.
| 2UVK position count | Rail clips |
|---|---|
| 2 | No rail clip |
| 3–5 | One rail clip |
| 6–24 | Two rail clips |
The 2UVK clip-quantity rule is specific to that model and is not extended to 2UVKM.
Specify the TB27 model and 5.08mm pitch, a two-digit position count from 02 to 24, the colour and any required configuration fields. The general terminal-block field guide does not expand this series beyond 24 positions.
