You get ten in the pack, they thread on hand-tight with no tools, and they fit any standards-compliant Micro connector. Simple insurance against the intermittent faults an open connector invites.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you've spent any time wiring up an NMEA 2000 network, you know the backbone and drop cables never end up perfectly matched to the number of devices you're running. You end up with a spare male connector or two hanging off a tee or a drop cable, pins exposed to whatever the bilge, engine room, or open helm throws at them. That's exactly what these Actisense screw covers are for. This is the 10-pack for the male Micro connectors, the plug end with the pins.\u003c\/p\u003e\n\u003cp\u003eHere's the thing about NMEA 2000 connections. They're weatherized when they're mated, but an open connector is a different story. Salt air, spray off the bow, condensation in a closed console, dust and grit in a lazarette. All of it goes straight for those exposed contacts. Give it a season or two and you've got green corrosion creeping across the pins, and that's when a solid network starts throwing intermittent faults that are miserable to chase down. A two dollar cover screwed on the day you rig the boat saves you that headache entirely.\u003c\/p\u003e\n\u003cp\u003eEach cover threads right onto the connector using the same locking collar you already know from the Micro standard. Snug it down by hand and it stays put. No tools, no adapters. Because they use the native NMEA 2000 Micro thread, they fit any standards-compliant network, whatever brand of backbone, tees, and drop cables you've built it from. If a connector meets the Micro-C spec, one of these caps it.\u003c\/p\u003e\n\u003cp\u003eThe pack gives you ten, which is the right number for most builds. A typical boat network runs five to seven devices, and once you account for spare tee ports and the odd unused drop, ten covers usually caps a whole boat with a few left in the spares bag. Keep the extras with your electrical kit. You'll reach for them the next time you add a sensor and free up a connector, or when you pull a display for the winter and want to protect the pigtail you left behind.\u003c\/p\u003e\n\u003cp\u003eOne detail worth getting right. This is the male version. It fits over a male connector, the end with the pins sticking out. If what you're staring at is an open female socket instead, the round port with the holes, you want the female version, the A2K-SCREWCAP-10-F. Grab the right one and it screws on clean. Grab the wrong one and it won't thread. When in doubt, look at the connector you're trying to cover. Pins means male, holes means female.\u003c\/p\u003e\n\u003cp\u003eA quick tip from years of rigging these. Before you screw a cover onto a connector that lives somewhere damp, wipe a little dielectric grease onto the contacts. It keeps moisture off the pins and makes the cover come off easy years later instead of fighting you. It's not required, the cover does its job on its own, but on an engine-room connection or anything down low near the bilge, it's cheap insurance.\u003c\/p\u003e\n\u003cp\u003eJust so we're clear on what these are and aren't. A screw cover protects an unused connector. It is not a terminating resistor, so it won't set the ends of your backbone. If you're looking to properly terminate the bus, that's a different Actisense part. And these aren't single use either. Screw one off to add a device, and when you free that connector up again later, the same cover goes right back on. Reusable, no wear from taking them on and off.\u003c\/p\u003e\n\u003cp\u003eThese are simple parts, but they're the kind of thing that separates a network that just works from one that nickels and dimes you with gremlins. Cap every open connector, keep water and salt off the contacts, and your NMEA 2000 bus stays quiet for years. That's the whole idea. Actisense builds the interfaces and gateways that a lot of these networks are built around, so they know exactly what a Micro connector needs to survive out on the water.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e10 protective covers per pack, enough to cap a typical 5 to 7 device NMEA 2000 network with spares left in the bag\u003c\/li\u003e\n  \u003cli\u003eFits male NMEA 2000 Micro (Micro-C) connectors, the plug end with the exposed pins\u003c\/li\u003e\n  \u003cli\u003eThreads on with the native Micro locking collar, hand-tight with no tools or adapters\u003c\/li\u003e\n  \u003cli\u003eStandards-based fit works with any compliant NMEA 2000 backbone, tee, or drop cable\u003c\/li\u003e\n  \u003cli\u003eKeeps salt spray, condensation, dust, and corrosion off unused connector contacts\u003c\/li\u003e\n  \u003cli\u003eReusable: screw off to add a device, screw back on later with no wear\u003c\/li\u003e\n  \u003cli\u003eSnugs down hand-tight and stays put through a rolling seaway\u003c\/li\u003e\n  \u003cli\u003eMade by Actisense, a specialist in NMEA 2000 interfaces and network hardware\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 Actisense 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 connectors do these covers fit?\u003c\/summary\u003e\n    \u003cp\u003eMale NMEA 2000 Micro (Micro-C) connectors, the plug end with the pins.
