Why the 4" × 4-1/2" plate matters

The 4" × 4-1/2" mounting plate has become a de-facto standard for medium duty casters due to its balance of footprint size, load distribution, and compatibility with common equipment frames. This allows OEMs and MRO teams to standardize replacements without redesigning mounting patterns.
