Rolls Straight Out

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 all necessary hardware included. It fits where your existing bottom tier sits, so no modification to the rest of the rack is needed at any point.

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.
Wheeled carriages and brackets. The L-angles are not included: you move them over from the bottom tier of the Synergy rack you already own.
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 tad pricey but worth it!

Here’s a cleaner, more polished version that keeps your tone and points intact while improving flow and clarity:

I went back and forth on buying this because of the price, but I can confidently say it was worth it. This has greatly helped me with handling my heavy dumbbells, and the movement is incredibly smooth. The only thing to be mindful of is rolling it in and out—there’s no guiding track or rail to assist with the transition, so you do need to be careful. That’s my only real gripe.

I’ll also note that I initially assumed the wheels were black, but they’re actually red. That said, it’s not an issue for me—I ended up liking the look. If anything, offering different wheel color options (black, white, green, purple, etc.) could make it even more appealing to buyers. Glow-in-the-dark wheels wouldn’t hurt either.

Overall, I’m thoroughly satisfied with this product and would definitely recommend it.

Very smooth rolling

This was a bit difficult to put together, I had a really hard time getting everything aligned (not sure why). However, it went together well, and now rolls amazingly smoothly (yes I've been to lazy to finish moving the dumbbells). I did have to swap the screws so the nut was outside, otherwise the rollers would get caught. Overall, this is a great way to both get more space on the shelf, and get access to the heaviest dumbbells!

Thank you for the honest review! We're glad to hear that, once assembled, the shelf is rolling smoothly and giving you extra space for your heavy dumbbells.
