Steel gauge & build
The rack's steel and construction decide how it handles heavy squats, pulls and kipping.
Steel gauge
11-gauge (≈3mm) or thicker steel is the commercial standard — lighter gauge flexes under heavy loads.
Hole spacing
Westside-style 1-inch hole spacing through the bench zone gives fine spotter-arm adjustment.
Footprint & base
A wide, stable base with bolt-down options prevents tipping under heavy use.
