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.\u003c\/p\u003e\n\n\u003ch3\u003eBuilt to take a beating\u003c\/h3\u003e\n\u003cp\u003eThe 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.\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 ranges.\u003c\/p\u003e\n\n\u003ch3\u003eTwo lengths for two purposes\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch3\u003eKey highlights\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSame shelf, two mounting angles: flat (rear lip) or 50° angled (front lip) — just use the alternate bolt holes\u003c\/li\u003e\n  \u003cli\u003e3mm formed steel shelf with a reinforced 6mm folded edge\u003c\/li\u003e\n  \u003cli\u003eWelded steel end brackets, 3× Ø17mm holes per bracket\u003c\/li\u003e\n  \u003cli\u003eFixes with M16×110mm bolts — matches MRR's 17mm hole \/ 16mm bolt standard\u003c\/li\u003e\n  \u003cli\u003eCompatible with Original MRR and Riot MRR\u003c\/li\u003e\n  \u003cli\u003eAvailable in 1075mm (1× crossmember) and 1675mm (1.5× crossmember) lengths for single or extended storage runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%;

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.\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 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I switch it from flat to angled later?\u003c\/strong\u003e\u003cbr\u003e\nYes — since it's the same shelf either way, you can unbolt it and remount it through the alternate holes if your storage needs change.\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 shelf is rated to 350kg and the 1675mm shelf to 400kg.
