SLM-1XS Small Metric Ball Base
The metric (SLM-1XS) ball base mounts to Metric plates with XS in the part number and to the Metric XS knuckles (SLM-2XS, SLM-2XS90, and SLM-2-2XS coupler). The XS (extra small) ball base has 2 holes for ease of mounting. The through hole can be used for routing wires, cables, or small hoses.
