They thread into your gimbal bracket and lock the display at the tilt angle you want. Lost one over the side or stripped the threads? This genuine Humminbird kit gets your screen locked back down in about five minutes.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Humminbird MKH-2 is the little part that keeps your fishfinder exactly where you set it. It's a set of two gimbal mounting knobs, the threaded knobs that thread into the sides of your gimbal bracket and clamp the display at the tilt angle you want. Lose one over the side, strip the threads after a few seasons, or buy a used unit that came without them, and this is the kit that gets you back on the water.\u003c\/p\u003e\n\u003cp\u003eThese are made for all Humminbird 800 and 900 Series units, and they fit the Humminbird ICE Flasher models too. If you're running a 900 Series head on a gimbal bracket at the console, these are the knobs Humminbird spec'd for that mount. The kit ships as a set of two, one for each side of the bracket, along with rubber washers that sit between the knob and the bracket to protect the finish and hold tension. It's the genuine part, not a generic substitute, so the threads match and the fit is right the first time.\u003c\/p\u003e\n\u003cp\u003eHere's the thing about mounting knobs: they take more abuse than people expect. Every time you tilt the screen to cut glare, every wave that rattles the console, every trailer mile down a rough road, those threads are working. Plastic knobs on an older unit go brittle from UV and salt over time, and eventually one cracks or spins free. When that happens the display flops around and you can't hold an angle, which is exactly the wrong problem to have when the fish are biting. A fresh set fixes it in about five minutes.\u003c\/p\u003e\n\u003cp\u003eInstallation is simple, but there's a right way to do it. Pull the old knobs and any old plastic inserts out of the gimbal bracket first. Don't force a new knob into a bracket that still has a broken piece jammed in it, because that's how you crack the bracket itself. Thread each knob in by hand, seat the rubber washer, and snug it down firmly. Hand tight is the goal. You're not torquing a lug nut. Over-cranking a plastic knob is the fastest way to strip it.\u003c\/p\u003e\n\u003cp\u003eIf you run a center console or any boat that sees real speed, a small tip from years of rigging these: put a dab of blue threadlocker on the threads before you install. Knobs can walk loose from vibration above 25 knots, and blue Loctite holds them without gluing them permanently. You'll still be able to back them off by hand when you need to pull the unit for winter storage. And speaking of the mount, these are designed for the original Humminbird gimbal mount. If you've moved your unit to an aftermarket ball mount you may not need them at all, so check your setup before ordering.\u003c\/p\u003e\n\u003cp\u003eCare is basic. Rinse the salt off when you rinse the rest of the boat, and store the unit covered when the boat sits, especially on aluminum hulls where the base of the knob can pick up corrosion over a season. Do that and a set of these lasts a long time. It's a cheap part that does one job well, and having a spare set in the console drawer is never a bad idea. Nobody wants to lose a knob at the ramp on opening day.\u003c\/p\u003e\n\u003cp\u003eBottom line: if your Humminbird 800 or 900 Series is wobbling in its bracket, missing a knob, or you just want a spare on hand, this genuine Humminbird set is the right fix. It's the exact part, it fits the way it should, and it gets your screen locked back down where you can actually read it.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eSet of two gimbal mounting knobs, one for each side of the bracket\u003c\/li\u003e\n  \u003cli\u003eGenuine Humminbird MKH-2 part (740082-1) for a direct fit with no modification\u003c\/li\u003e\n  \u003cli\u003eFits all Humminbird 800 and 900 Series units\u003c\/li\u003e\n  \u003cli\u003eAlso fits Humminbird ICE Flasher models\u003c\/li\u003e\n  \u003cli\u003eIncludes rubber washers that protect the bracket finish and help hold tension\u003c\/li\u003e\n  \u003cli\u003eHand-tighten install with no tools, swaps in about five minutes\u003c\/li\u003e\n  \u003cli\u003eClamps the display at your chosen tilt angle to cut glare\u003c\/li\u003e\n  \u003cli\u003eDesigned for the original Humminbird gimbal mount\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Humminbird reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat comes in the MKH-2 kit?\u003c\/summary\u003e\n    \u003cp\u003eA set of two gimbal mounting knobs, one for each side of the bracket, plus rubber washers that sit between the knob and the bracket to protect the finish and hold tension.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWill these fit my Humminbird 900 Series?\u003c\/summary\u003e\n    \u003cp\u003eYes.
