Rolls Straight Out
Reach the bottom tier
Guided or Non-Guided
With or without railing
Replaces Your Bottom Tier
Direct swap, same footprint
11 Gauge Steel
Built to take a loaded tier
The bottom tier of a horizontal rack is the one you crouch for. This makes it roll out instead, so the weights come to you. It is a direct replacement for the tier you have, keeps the same footprint, and comes guided with railing or non-guided without, depending on how much lateral control you want.
Guidance:Non-Guided (No Railing)
Designed & Built in Florida
Every rack is made to order and manufactured in-house to ensure premium quality.
Effortless Roll-Out Design
Simple extension for quick retrieval of dumbbells, plates or other gear. No complex mechanism to go wrong, just a tier that comes out to meet you instead of making you reach into the back.
Space-Optimizing Replacement
It integrates as a direct replacement for the bottom tier of your horizontal rack, so the rack keeps its compact footprint and gains mobility. Nothing about the outside dimensions changes.
Guided or Non-Guided
Guided adds railing that keeps the tier tracking straight as it comes out. Non-guided leaves it off for a simpler, more open action. Pick whichever suits how heavily you load the bottom tier.
Modular Compatibility
Fully compatible with your horizontal rack, so it fits into upgrades and expansions rather than locking the rack into one configuration. The rest of the rack is untouched.
Built for the Load
Crafted from durable 11 gauge steel, which is the same material used through the rest of the storage line. The bottom tier carries the heaviest weights, and this is built accordingly.
Quick Assembly
Straightforward setup in minutes with the hardware included. Since this is the wheels only, it assumes the L-angles and brackets are already fitted to the rack you are attaching them to.
What This Is The wheels only. Buy this ONLY alongside a new Synergy horizontal rack, which already ships with the L-angles and brackets.

Frequently Asked Questions
Pick by what you already have. All three finish as the same rolling bottom tier.

Buying a new Synergy horizontal rack in the same order? Get the Roll-Out Add-on (wheels only). The rack ships with the brackets and L-angles.

Already own a Synergy horizontal rack? Get the Upgrade Kit (wheeled carriages and brackets). You move the L-angles over from your current bottom tier.

Want the complete tier with every part new? Get the Roll-Out Shelf (wheeled carriages, brackets and L-angles), in 43" or 70" wide.
The wheels only. Order it with a new Synergy horizontal rack, which ships with the brackets and L-angles. If you already own your rack, you need the Upgrade Kit or the Roll-Out Shelf instead.
Guided includes railing that keeps the tier tracking straight as it rolls out, which helps when the bottom tier is heavily loaded or when you pull it out one-handed.

Non-guided leaves the railing off for a simpler action and a more open tier. Both roll; the difference is lateral control.
It is built for Synergy horizontal storage racks and replaces the bottom tier directly.

It is not recommended for Bravo models. If you have a Bravo horizontal rack, this is not the right upgrade.
Because the bottom tier is the one you crouch and reach into. Rolling it out brings the weights to you at the front of the rack, which matters most with heavy dumbbells where the reach is awkward and the load is worst.
No. It is a direct replacement for the tier you already have, so the rack keeps the same footprint. The only thing that changes is that the bottom tier now extends.
Straightforward setup in minutes with all necessary hardware included. It swaps in where your existing bottom tier sits, so there is no modification to the rest of the rack.

A much needed add-on

A much-needed add-on for the Alpha 4-Tier Horizontal Rack. It holds the heavier dumbbells perfectly and rolls out surprisingly smoothly, even under a lot of weight. The build quality is outstanding just like all Synergy Fitness products, it’s built like a tank.

I’ve been using this setup heavily for about two months now and would highly recommend it. My only small gripe is that it could use retractable guiding rails attached to both the rack and the roller. When pushing it back under the main rack, aligning it perfectly can be tricky since there’s minimal clearance on each side. Even when centered, I often have to adjust it once or twice so it doesn’t catch.

One extra bonus: this add-on creates more space between the upper shelves, making it easier to grab and rerack dumbbells. I’ll still need to adjust the upper shelves down a bit more, but overall, this is an excellent and worthwhile addition.

Thank you for the detailed review! We're glad the roll-out shelf is handling your heavier weights smoothly, and we really appreciate your feedback regarding guide rails.
