SXK HMMR RBA Bridge for Billet / BB / Boro Tank DL / RDL / MTL, Blind / 1mm / 2mm Inserts

316 stainless steel construction
Inserts for airflow control

Comes with 7 PCS airflow inserts:
2 PCS inserts with 1 hole (1mm)
2 PCS inserts with 2 holes (2mm)
2 PCS short inserts to use the full airflow (4mm, pre-installed)
1 PC insert blind without holes

The RBA is side airflow but airflow comes from the bottom, the path that the airflow goes makes the inserts to a new "logic", not like the inner diameter of classic airflow pins, so here we will post our recommendation for different types of drags.

2 short inserts for full airflow
1 short insert and 1 of the others
For RDL:
2 inserts with 2 holes
1 insert with 2 holes and 1 insert with one hole
For MTL:

1 insert with 2 holes and 1 insert without holes
1 insert with 1 hole and 1 insert without holes
