Mounting every driver separately on Unistrut takes careful measuring to keep the spacing even. The MB-9 does that measuring for you. It holds \u003cstrong\u003enine drivers\u003c\/strong\u003e on a single bar, for a total of \u003cstrong\u003e810 watts\u003c\/strong\u003e. Driver positions sit about 5.25 in apart, the tightest layout of the four MB bars. That close spacing suits flowering rooms that need high PPFD from each fixture. The bar measures \u003cstrong\u003e45.35 in\u003c\/strong\u003e long and 2.21 in wide. It works with both the two-channel TLD-2 and the four-channel TLD-4 drivers. The package contains one MB-9 bar. Its listed product weight is 870 g, or about 1.92 lbs.\u003c\/p\u003e\u003ch2\u003eHanging a Model One Mounting Bar\u003c\/h2\u003e\u003cp style=\"text-align: justify;\"\u003eThere are two ways to install the bar. For direct hanging, attach the provided hangers to the bar and suspend it from the ceiling. For Unistrut, loosely thread two Unistrut nuts onto the bar, slide it into the channel and tighten the nuts. Each driver then twists about 25 degrees to lock onto its position. Alternate the direction of each driver so the male and female power leads meet the right neighbor. TDC daisy-chain cords link driver to driver, and a TDC-120, TDC-240 or TDC-277 cord feeds the group. The Model One manual limits how many drivers one feed cord can carry, from 11 at 120V to 25 at 277V. Once the drivers are power-linked, press each LED bar into its driver until it clicks. For lower-intensity areas, the MB-4, MB-7 and MB-8 bars space fewer drivers farther apart. The Model One system manual attached below covers every step with diagrams.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eNine Driver Positions:\u003c\/strong\u003e Holds nine Model One drivers for an 810W fixture on one bar.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre-Set Spacing:\u003c\/strong\u003e Fixed driver positions keep light output even without measuring on site.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo Mounting Options:\u003c\/strong\u003e Hang directly from the ceiling or lock into standard Unistrut.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwist-Lock Drivers:\u003c\/strong\u003e TLD-2 and TLD-4 drivers twist onto the bar in seconds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-PPFD Layout:\u003c\/strong\u003e The tightest spacing in the MB series suits flowering rooms.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background-color:#333; color:#fff;\"\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003ePart number\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eMB-9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eDriver capacity\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e9 × TLD-2 or TLD-4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eTotal power\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e810W (9 × 90W)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eLength\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e45.35 in (1152 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eWidth\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2.21 in (56.1 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eDriver spacing\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e5.25 in (133.3 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eMounting\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eDirect hang or Unistrut\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1.92 lbs (870 g)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003ePackage contents\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1 × MB-9 mounting bar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"ThinkGrow","offers":[{"title":"Default Title","offer_id":50528181747926,"sku":"MB-9","price":26.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/thinkgrow-mb-9-main-v1.webp?v=1790264279","url":"https:\/\/growershouse.com\/products\/thinkgrow-quick-release-mounting-bar-for-9-drivers-810-watt-mb-9","provider":"GrowersHouse","version":"1.0","type":"link"}
