| Inside Gap Dimension | 4.32" (the spacing of the inside gap of the Vertical Add-on where your hand goes, not the required dumbbell handle size) |
| Spacing Between Vertical Add-ons on the Same Side | Approximately 12" (measure your largest dumbbell head width before pairing two Vertical Add-ons on the same end; 2 Alpha Elite sets or an Alpha + Elite combination on the same side typically will not fit due to larger dumbbell heads) |

Frequently Asked Questions
No. This listing is for the rack only. Dumbbells, kettlebells, and plates are sold separately. Dumbbells shown in product photos are for illustration. The rack does include all the hardware and tools you need to assemble it. You can browse compatible accessories under "Pick Your Accessories" above.
The Double-Post version has 4 uprights instead of 2. The extra uprights let you mount up to 2 sets of Alpha Vertical Add-ons (one on each end), effectively doubling your vertical dumbbell storage capacity compared to the standard 2-upright 4-Tier. The frame, shelves, hardware, and dumbbell capacity per shelf are otherwise identical.
Typically no. There is approximately 12 inches of spacing between Vertical Add-ons mounted on the same side of the rack, and Alpha Elite holds larger, heavier dumbbells whose heads usually exceed that clearance when paired side by side. The same limitation applies to running 1 Alpha + 1 Alpha Elite on the same side. Two sets of standard Alpha Vertical Add-ons (for lighter 5-45 lb dumbbells) generally fit without issue. Before ordering an Elite pairing, measure the widest head of the dumbbells you plan to store and compare to the 12-inch spacing. If you're unsure, email support@synergycustomfitness.com with your dumbbell brand and weights and we'll confirm compatibility.
Our Flat Shelf Add-on is the best option for storing kettlebells, medicine balls, and other accessories.
Absolutely. All of our shelves are built so that you can change the angle and the position of each tier.
The most popular is a 4-Tier 70" with flat panel add-ons and vertical dumbbell holder add-ons. With the Double-Post you can scale this further by adding a second set of Vertical Add-ons on the opposite end.
Yes, you can store plates in two different ways on our horizontal rack. The first is to use our L-Angle Supports (with added adapters) to store the plates on the top tier of the rack. The second is to use our Plate Holder attachment on the sides of the rack to slide the plates in.
If you have additional 5-45 lb dumbbells to store, or you want a flat panel on top for kettlebells but still need additional dumbbell storage space, the Vertical Add-ons are a strong upgrade. The Double-Post lets you add up to 2 sets, one on each end. Keep in mind that Vertical Add-ons will limit your use of accessories on the sides of your rack where they are mounted.
Yes, as long as your dumbbell handles are 5 inches or longer.
The 4-Tier Horizontal Rack Double-Post comes with a Limited Lifetime Warranty on the frame and a 30-day hassle-free return policy. Questions about a specific issue? Email support@synergycustomfitness.com or call 877-305-4057.
