The \u003cstrong\u003eMRR Shelf – Wallball\u003c\/strong\u003e is an open twin-rail storage system that bolts directly onto your MRR uprights, giving those items a dedicated home without the clutter of a solid shelf they don't actually need.\u003c\/p\u003e\n\n\u003ch3\u003eOpen rail design, built for round and irregular loads\u003c\/h3\u003e\n\u003cp\u003eUnlike the solid MRR Shelf for dumbbells and kettlebells, this is a through-construction rail system: two parallel rails set 240mm apart instead of a closed deck. That gap is exactly what makes it work for wall balls, bumper plates and similar equipment — items nest and rest across the rails rather than needing a fully enclosed surface, and any dust or grip chalk falls straight through instead of collecting on a shelf.\u003c\/p\u003e\n\n\u003ch3\u003eSolid tube construction\u003c\/h3\u003e\n\u003cp\u003eEach rail is formed from 38×38×3mm square steel tube, welded to a triangular end bracket at each end for a rigid, twist-free structure across the full length.\u003c\/p\u003e\n\n\u003ch3\u003eStraightforward MRR mounting\u003c\/h3\u003e\n\u003cp\u003eEach 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 rig and rack ranges.\u003c\/p\u003e\n\n\u003ch3\u003eTwo lengths for two purposes\u003c\/h3\u003e\n\u003cp\u003eThe 1075mm rail matches a single MRR crossmember\/nameplate width, ideal for a single storage bay.

The open, twin-rail design lets them rest securely across the gap while letting dust and chalk fall through, and it keeps the unit lighter than a solid deck of the same length.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill this fit my rig and rack?\u003c\/strong\u003e\u003cbr\u003e\nIt'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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between the 1075 and 1675 versions?\u003c\/strong\u003e\u003cbr\u003e\nLength only — everything else is identical. The 1075mm rail matches one MRR crossmember width and suits a single storage bay; the 1675mm rail spans 1.5 crossmember widths for a longer, uninterrupted run, handy for lining up multiple wall balls or plates.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use this for dumbbells or kettlebells too?\u003c\/strong\u003e\u003cbr\u003e\nIt's designed and dimensioned for wall balls, bumper plates and similar bulky items. For dumbbells and kettlebells, our solid MRR Shelf – Dumbbell\/Kettlebell (with its closed deck and raised lip) is the better fit.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat hardware is included, and what do I need to install it?\u003c\/strong\u003e\u003cbr\u003e\nEach 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much weight can it hold?\u003c\/strong\u003e\u003cbr\u003e\nThe 1075mm rail is rated to 350kg and the 1675mm rail to 400kg.
