Column Sentry - Steel Reinforced Upright Frames

Accidental lift truck impact damage is inevitable, but the unique Column Sentry™ reinforcing keeps it to an absolute minimum.
• Single Heavy 7 gage (3/16”) Internal Channel
• One design with improved performance vs. previuos design of CSI & II
• New Channel accommodates field drilled side holes and bolts as needed
Column Sentry™ reinforcing is heavy gage steel channel welded inside the column providing exceptional resistance to impact damage of frame columns. Column Sentry™ reinforcing helps guard against rack failure, collapse, and local buckling; at the same time, it increases column load carrying strength. And that's not all. Column Sentry™ reinforcing is compact, thereby, saving critical aisle space. No more space is required than our standard column, and it need be applied only in critical areas such as floor to first beam level on front columns (aisle side).
No other reinforcing method offers the protection, strength, and economy of Column Sentry™.

Guillotine Impact Testing best simulates the impact of a lift-truck fork.
Measuring Impact Resistance offers the most accurate assessment of how a column will respond when subjected to "typical abuse" in warehousing environments. Other tests, such as Load Tests, only measure the ability of a column as it relates to capacities.
Resistance to Impact
Adding Ridg-U-Rak's Column Sentry™ reinforcing results in a composite column section that increases column strength by as much as 240%, as well as increasing torsional resistance several hundred times. This results in an upright frame that is extremely resilient, impact resistant, economical and most importantly, provides tremendous residual carrying capacity after an impact occurs!
