{"product_id":"mrr-wall-stringer","title":"MRR Wall Stringer","description":"\u003cp\u003eA rack is only as solid as what it's bolted to. The MRR Wall Stringer is the foundation behind a proper wall-mounted MRR setup — a 1400 mm profiled steel plate that adapts the MRR bolt pattern to your wall and spreads the load of the rack across a large surface area for a connection you can trust.\u003c\/p\u003e\n\u003cp\u003eThe stringer's dense grid of mounting slots and round fixing holes lets you hit wall structure at almost any spacing, while the profiled 3 mm steel keeps the plate rigid across its full 1400 mm span. Two rows of Ø17 mm utility holes add genuine storage functionality — hang bands, belts, jump ropes, collars, or any standard hook-mounted accessory directly on the stringer. It's a mounting plate and a storage wall in one.\u003c\/p\u003e\n\u003cp\u003eCompatible with Riot MRR, Riot Rig, and Original MRR.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eDetail\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverall dimensions\u003c\/td\u003e\n\u003ctd\u003e1400 x 290 x 33 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUsable inner length\u003c\/td\u003e\n\u003ctd\u003e1167 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSteel thickness\u003c\/td\u003e\n\u003ctd\u003e3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProfile depth\u003c\/td\u003e\n\u003ctd\u003e33 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting hole diameter\u003c\/td\u003e\n\u003ctd\u003eØ17 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUtility hole diameter\u003c\/td\u003e\n\u003ctd\u003eØ17 mm (2 rows)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHole pitch (close)\u003c\/td\u003e\n\u003ctd\u003e25 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHole pitch (wide)\u003c\/td\u003e\n\u003ctd\u003e50 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSection spacing\u003c\/td\u003e\n\u003ctd\u003e200 mm \/ 450 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlot dimensions\u003c\/td\u003e\n\u003ctd\u003e40 x 12 mm (oblong)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eMild steel, black powder coat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eRiot MRR, Riot Rig, Original MRR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003e\n\u003cbr\u003eFAQ\u003c\/h2\u003e\n\u003ch3\u003eWhat does the Wall Stringer actually do?\u003c\/h3\u003e\n\u003cp\u003eIt bridges the gap between MRR components and your wall. Rather than mounting your rack uprights or rig directly to a handful of wall fixings, the Wall Stringer spreads the load across a 1400 mm plate with a dense grid of fixing points — giving you a far more robust and reliable wall connection. It also translates the MRR bolt pattern so everything lines up correctly, regardless of what's behind the wall.\u003c\/p\u003e\n\u003ch3\u003eWhich products should I use it with?\u003c\/h3\u003e\n\u003cp\u003eThe Wall Stringer is compatible with Riot MRR, Riot Rig, and the Original MRR. It's the recommended base for any wall-mounted MRR setup — particularly the Riot MRR Folding Crossmember system, where the stringer provides the solid backing needed to handle folding forces and repeated loading cycles. It's equally at home behind a Riot Rig or Original MRR installation where you want maximum confidence in the wall connection.\u003c\/p\u003e\n\u003ch3\u003eWhat are the utility holes for?\u003c\/h3\u003e\n\u003cp\u003eThere are two rows of Ø17 mm utility holes running the length of the stringer. These accept standard storage hooks for bands, jump ropes, belts, collars, chalk bags, and mobility tools — turning the stringer into a storage wall as well as a mounting plate. You can also use them to attach other MRR items directly to the stringer if your setup calls for it.\u003c\/p\u003e\n\u003ch3\u003eHow is it fixed to the wall?\u003c\/h3\u003e\n\u003cp\u003eThe stringer's oblong mounting slots (40 x 12 mm) and dense round hole pattern give you plenty of options to hit studs, concrete anchors, or timber noggins at almost any spacing. The 1400 mm length means you can span multiple fixing points easily, and the profiled 3 mm steel keeps it rigid across the full span.\u003c\/p\u003e\n\u003ch3\u003eDoes it come finished?\u003c\/h3\u003e\n\u003cp\u003eYes — the Wall Stringer is black powder coated mild steel, matched to the rest of the MRR and Riot range.\u003c\/p\u003e\n\u003ch3\u003eHow deep does it sit off the wall?\u003c\/h3\u003e\n\u003cp\u003eThe profiled section is 33 mm deep, so the stringer sits just 33 mm proud of the wall surface before your uprights or rig brackets attach to it.\u003c\/p\u003e\n\u003ch3\u003eDoes the Wall Stringer come with wall fixings\/wall anchors?\u003c\/h3\u003e\n\u003cp\u003eNo — wall fixings are not included. The correct fixings depend entirely on your wall construction: timber stud walls, solid brick or block, concrete, and drywall over steel frame all require different anchors, bolt sizes, and load ratings. We recommend having the installation assessed by a qualified person who can specify the right fixings for your wall type and confirm the fixing points can handle the load. The stringer's slot and hole pattern is designed to give maximum flexibility to hit solid structure whatever your wall spacing.\u003c\/p\u003e","brand":"Strength Shop","offers":[{"title":"Default Title","offer_id":57136478945545,"sku":"WM-STRINGER-MRR","price":151.0,"currency_code":"CHF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0564\/6113\/1956\/files\/sts-shop-wall-stringer-home-gym-rack-rig-station-powerlifting-calisthenics-bodyweight-training2.jpg?v=1782129571","url":"https:\/\/strengthshop.ch\/products\/mrr-wall-stringer","provider":"Strength Shop","version":"1.0","type":"link"}
