A cluttered free-weight area slows everyone down and creates a safety hazard, which is exactly why Body-Solid built its SDKR modular storage rack system as a family rather than a single one-size-fits-all product. If you're comparing the Body-Solid SDKR modular storage rack lineup, the choice comes down to what you're actually storing: straight dumbbells, kettlebells, or dumbbells on saddle-style tiers. Here's how the SDKR-DB, SDKR-KB, and SDKR-SD differ.
All three racks share the same modular design philosophy — tiered, commercial-use storage meant to be arranged along a wall or used to anchor a free-weight zone — and all three start in a similar price band, so the decision is really about tier geometry matched to your equipment, not budget tiering.
SDKR-DB Modular Storage Rack with Dumbbell Tiers
Price: $975 | Application: Commercial | Type: Dumbbell Storage
The SDKR-DB is built around standard horizontal dumbbell tiers, the layout most commercial gyms default to for a straight dumbbell rack run. It's the most straightforward of the three and the natural starting point if you're simply racking a standard dumbbell set in ascending order along a wall.
Best for: Gyms organizing a standard dumbbell rack run without kettlebells or specialty racking needs.
SDKR-KB Modular Storage Rack with Kettlebell Tiers
Price: $940 | Application: Commercial | Type: Kettlebell Storage | Warranty: Body-Solid Full Commercial/Lifetime Warranty
The SDKR-KB swaps in tiers shaped for kettlebells specifically, which sit and stack differently than dumbbells due to their handle and rounded-bell geometry. If your free-weight area includes a kettlebell selection, dedicated kettlebell tiers keep them from rolling or sitting awkwardly the way a flat dumbbell tier would. It's backed by Body-Solid's Full Commercial/Lifetime Warranty.
Best for: Gyms with a dedicated kettlebell selection that need tiers shaped to hold them securely.
SDKR-SD Modular Storage Rack with Dumbbell Saddle Tiers
Price: $940 | Application: Commercial | Type: Dumbbell Saddle Storage
The SDKR-SD uses a saddle-style tier design for dumbbells rather than the flat horizontal tiers on the SDKR-DB. Saddle tiers cradle each dumbbell head individually, which can help keep a long run of dumbbells visually organized and prevent the sideways drift you sometimes get on flat tiers in a high-traffic area.
Best for: Gyms that want a more structured, individually-cradled dumbbell storage layout rather than open horizontal tiers.
