How Strong Is ARackAbove?

The Super Simple Engineering Proof

Independent structural calculations by Celtic Engineering, Inc. prove that our floor-supported rack systems safely hold up to 2,000 lbs with Zero Ceiling Load.

The Big Difference: Why Floor Support Matters

EXECUTIVE SUMMARY FOR HOMEOWNERS

Traditional Ceiling-Mounted Racks

Add lasting weight to your home’s roof trusses. If the roof cannot carry the load, trusses can split, gusset plates can separate, and structural failure can cause costly damage or serious injury. A rack’s weight rating does not tell you what your ceiling can safely hold.

The ARackAbove System

Unlike ceiling racks, ARackAbove carries your stored weight directly to the garage floor—transferring 100% of the weight down to solid concrete floor. Adjustable legs and leveling feet create unmatched stability—removing all weight and liability from your roof.

Load Testing Highlights

Calculated across 1-Car and 2-Car Garage Models

1-Car Garage Unit Rectangular Tube
1,300 lbs

Total Capacity (24.1 – 32.5 PSF Rating)

Built with heavy-duty 1-3/4" x 2-3/4" x 0.110" rectangular aluminum tubing across a 48" × 10'–13.5' span. Supports up to 32.5 lbs per square foot.

Utilization Ratio: 0.97 (Passed)
2-Car Garage Unit Rectangular Tube
2,000 lbs

Total Capacity (22.73 PSF Rating)

Built using 1-3/4" x 2-3/4" x 0.110" rectangular aluminum tubing across a 48" × 22' span. Carries nearly 23 lbs per square foot across 88 sq ft.

Utilization Ratio: 0.997 (Passed)
Roof Truss Load Zero Roof Stress
0 lbs

Weight Hanging From Ceiling

Unlike traditional hanging racks, zero weight pulls down on your ceiling framing. All load rests squarely on the concrete slab.

Slab Safety Rating: 100% Floor Supported
