MRR Shelf - Dumbbell/Kettlebell

The MRR Shelf – Dumbbell/Kettlebell turns unused rig and rack space into smart, secure storage, bolting directly onto your MRR uprights so your equipment has a proper home, right where you train.

One shelf, two mounting positions

This is the clever part: it's the same shelf in both configurations, just bolted through a different set of holes in the end bracket. Mount it flat and the raised 50mm lip sits at the back, stopping kettlebells and loose gear from being pushed off behind. Mount it at a 50° angle and that same lip sits at the front, so dumbbells naturally rest against it instead of rolling off the front edge. Pick whichever suits the equipment you're storing, or run both configurations across your rig or rack.

Built to take a beating

The shelf is formed from 3mm steel plate with a folded 6mm edge for extra rigidity, so it won't oil-can or flex under a full load of iron. The end brackets are welded steel, drilled for a secure two-point fixing at each end.

Straightforward MRR mounting

Each end bracket uses 17mm holes and fixes with an M16×110mm bolt, matching MRR's standard hole and bolt spec exactly — no adapters, no workarounds. It's fully compatible with both the Original MRR and Riot MRR ranges.

Two lengths for two purposes

The 1075mm shelf matches a single MRR crossmember/nameplate width, ideal for a single storage bay. The 1675mm shelf spans 1.5× that width for a longer run of continuous storage, perfect when you want one uninterrupted shelf instead of two separate ones.

Key highlights

• 3mm formed steel shelf with a reinforced 6mm folded edge
• Welded steel end brackets, 3× Ø17mm holes per bracket
• Fixes with M16×110mm bolts — matches MRR's 17mm hole / 16mm bolt standard
• Compatible with Original MRR and Riot MRR
• Available in 1075mm (1× crossmember) and 1675mm (1.5× crossmember) lengths for single or extended storage runs

Specifications

FAQ

What's the difference between the flat and angled mounting positions?
It's the same physical shelf — you just bolt it through a different set of holes in the end bracket. Flat mounting puts the raised lip at the back, which is great for kettlebells or anything you don't want sliding off behind. Angled mounting (50°) puts the lip at the front, which naturally holds dumbbells against it instead of letting them roll forward.

Will this fit my rig and rack?
It's built to the MRR hole and bolt standard (17mm holes, M16 bolts), so it's compatible with both the Original MRR and Riot MRR rig and rack ranges. If you're on a different rig system, check your upright hole spacing and diameter against these specs first.

What's the difference between the 1075 and 1675 versions?
Length only — everything else about the shelf is identical. The 1075mm shelf matches one MRR crossmember width and suits a single storage bay; the 1675mm shelf spans 1.5 crossmember widths for a longer, uninterrupted run of shelf storage.

Can I switch it from flat to angled later?
Yes — since it's the same shelf either way, you can unbolt it and remount it through the alternate holes if your storage needs change.

What hardware is included, and what do I need to install it?
Each end bracket fixes with an M16×110mm bolt through the 17mm mounting holes. You'll just need a spanner/Allen key sized to the bolt head to fit it to your rig.

How much weight can it hold?
The 1075mm shelf is rated to 350kg and the 1675mm shelf to 400kg. If you need a confirmed figure for a specific setup, get in touch and we'll be happy to help.
