Post capacities are based on the maximum vertical distance between left or right beams or front-to-back beams,whichever is greater. In single rivet beam units, the vertical distance between front-to-back beams will usually govern.

Tie plates must be spaced no more than 48 inches apart to insure structural stability when joining angle post together.All units require tie plates at top and bottom.

The above capacities are not intended for use when designing multi-level systems or for specific requirements whereseismic forces are a factor. For specific multi-level or seismic requirements contact your Hallowell Sales Manager.

All units must have a full perimeter of double rivet beams at the top and bottom to insure a stable and rigid unit. All units using single rivet beams 10’0” to 18’0” in height, require an additional double rivet perimeter beam level located approximately in the middle of the unit.

All single rivet beam units must have one (1) intermediate pair of front to back beams for 7’0” and 8’0” high units and (2) intermediate pair of front to back beams for 9’0” high units. For 10’0” to 18’0” high units refer to the above paragraph. DO NOT exceed 48” between front to back beams.
Single Rivet and Double Rivet Front-to-Back Beams may be common when using T-Posts on units up to 8’ high.

All intermediate single rivet levels over 24
inches deep must also have single rivet beams supporting the particle board front to back.

All double rivet beam units must have front to back beams at each shelf level.
