What measurements do I need to match teardrop beams to existing uprights?
Quick Answer
To match new teardrop beams to your existing uprights, measure six things: 1) vertical hole pitch and slot shape, 2) column depth and face width, 3) lug spacing on the original connectors, 4) clear inside-to-inside beam span, 5) beam face/step size, and 6) required shelf capacity rating.
Detailed Answer
Start by confirming the upright hole pattern—a quick warehouse optimization check. On most roll-formed “universal” or “teardrop” frames the slots repeat every 2.0 inches, but older rack sometimes use 3-inch or offset spacing. Place a tape against one column flange and note the center-to-center distance between three consecutive holes; this figure must match the vertical lug spacing on the replacement beam connector.
Next note the slot profile. A true teardrop opening has a ½-in. round top that narrows to roughly 3⁄8-in. in the neck. If the neck is wider or squared, you may be dealing with an Interlake New Style, Ridg-U-Rak “slotted,” or another proprietary pattern and the beam must come from that manufacturer.
Measure the column depth (front-to-back) and width (left-to-right across the face) so the connector plates seat flush without twisting. Then record:
- Clear span between inside faces of opposing uprights—this is the beam length you will order.
- Beam face height and step depth (for step beams) to hold wire decking or pallet supports.
- Desired load capacity, because two beams working as a pair must support the shelf without exceeding either the beam or upright rating.
If any dimension is uncertain, Warehouse Cubed’s warehouse consulting services team can perform an on-site rack audit, match compatible pallet racking systems from Interlake Mecalux or Unarco, and integrate the beams into a broader material handling systems integration plan—complete with pallet rack repair, safety audits, and future-ready warehouse automation solutions.
