Hey there! If you’ve ever looked at a cable tray system and thought, “That’s just metal tracks for wires,” let me stop you right there. Yeah, the main trays are the backbone of any setup—whether it’s a big warehouse, a new office building, or a data center with more cables than a fish tank has water—but the real magic is in the accessories. As someone who’s been in the cable tray supply game for years, I’m here to break down all the little parts that make a basic tray system actually work, no boring jargon, just real talk. Cable Tray Systems
First off, let’s get one thing straight: cable trays aren’t one-size-fits-all. If you’re running cables around a sharp corner, going up a wall, or just want to keep things neat so no one trips, you need accessories. And not just any accessories—ones that fit your specific tray type (we’ve got ladder, solid, and perforated trays, for the record) and hold up to whatever environment you’re in (think outdoor rain or super hot industrial floors). Let’s dive into the most common ones, because trust me, you’ll need at least a few of these.
Starting with the basics: support brackets. Wait, no, hear me out—these aren’t just random metal bits. They’re what hold the tray up, so if these are garbage, the whole system goes wobbly. We’ve got different kinds for different jobs. There’s wall-mounted brackets that screw straight into concrete or brick—perfect if you’re running trays along a building’s side. Then there’s ceiling brackets, which hook onto exposed rafters or drop ceiling grids; great for office spaces where you don’t want to drill into every wall. Oh, and don’t forget rod hangers—those are the ones that connect to the ceiling and have a clip or hook for the tray. We even have adjustable ones, so if your ceiling’s a little uneven, you don’t have to force the tray to fit. Pro tip: always get brackets made from the same material as your tray. If you’re using galvanized steel, don’t mix in a cheap aluminum bracket—they’ll corrode where they touch, and that’s a headache you don’t need.
Next up, elbows. Yeah, corners. If you had straight trays only, you’d never turn a corner, and that’s not helpful when a wall’s in the way. Elbows come in all angles: 45-degree, 90-degree, even straight 180s to go back the other way. Wait, and there’s more than just the angle—there’s inside and outside elbows too. Like, if your tray is running along a wall and needs to turn inward to go around a pillar, you use an inside elbow. And if you’re going around a sharp edge outside, outside elbow. What’s cool is that some elbows are pre-bent, but we also sell slip-on elbows that you cut to fit the exact angle you need. Saves you from buying a bunch of different pre-made ones for weird spaces. Just make sure the elbow is the same width as your tray—no point in a 12-inch elbow for a 6-inch tray.
Then there’s tees and crosses. These are for when you need to branch off a tray into two or three directions. Tees are T-shaped—like, main tray goes one way, and a branch comes off the side. Perfect if you’re running a main line down a hallway and need to split to different rooms or workstations. Crosses are for four directions, like if you’re at a big junction where cables need to go left, right, forward, and back. We even have reduced-tees, where the branch is narrower than the main tray—great if you need a smaller line going off to a smaller area. No matter which one you get, they keep cables organized so you’re not just running a bunch of loose wires everywhere, which is a fire hazard if you ask me.
Let’s talk about something people sleep on: cable gland connectors. Wait, no, these are super important. Glands are the seals at the ends of trays (or where you branch off) that keep dust, water, or even bugs out—critical if you’re working outdoors or in a dusty factory. They also grip the individual cables so they don’t pull out if something yanks on the tray. We have different types: compression glands for tight, heavy-duty jobs, and quick-release glands if you need to add or remove cables fast. And if you’re working with big, thick power cables, we’ve got extra-large glands that fit right, no crimping required. Another thing: if you’re running cables into a cabinet or switchgear, there are also tray-to-enclosure adapters that connect the tray directly to the box—no loose gaps where moisture can get in.
Oh, and splice plates. Because trays don’t magically come in 100-foot lengths (wish they did, but real life’s not like that). If you’re running a long line and need to connect two tray sections together, you need a splice plate. It’s a flat metal strip that bolts over the joint between two trays, making it tight so the tray doesn’t sag or separate. We also have splice plates that come with grounding tabs—super important for electrical safety, because you want the whole tray system to be grounded to prevent shocks or electrical interference. Skip the cheap splice plates that don’t have these—you’ll regret it when a cable gets damaged.
What about when you need to raise or lower a tray? That’s where riser clamps or riser fittings come in. Risers are the parts that go straight up a wall or column, right? So instead of bending a tray up, you use riser clamps that hold the tray vertical. Some risers are adjustable, so you can set them to go up at any height, and they work with all tray types. If you’re going up a very tall wall, we have multi-piece riser sections so you don’t have to lift a 10-foot one all at once. And don’t forget to pair risers with extra support brackets—vertical trays are heavier, so you need more brackets to keep them from tipping.
Wait, let’s not forget about cable separators and dividers. Especially in data centers or industrial setups where you have power cables and data cables running together. If you mix those, you get electrical interference—data cuts out, power gets wonky. Separators are little plastic or metal tabs that snap into the tray, splitting it into sections so power cables stay on one side, data on the other. We have different sizes: small separators for thin control cables, big ones for thick power lines. They’re super easy to install—just push them into the tray’s slots, no tools needed. No more digging through a mess of cables to find one line.
And for outdoor or high-moisture environments? There are weatherproof end caps. The ends of trays are open, so rain, snow, or dust can get in and damage cables. End caps seal those ends tight—made from galvanized steel or even PVC for extra corrosion resistance. Some even have drainage holes if you do get moisture inside, so water doesn’t pool and rot the cables. If you’re on a roof or a loading dock, these end caps are non-negotiable—trust me, I’ve seen too many projects where they skipped these and had to replace all their outdoor cables a year later.
Oh, and let’s mention grounding accessories, because safety isn’t something to cut corners on. We have grounding jumpers—short metal cables with connectors on both ends—that connect different tray sections so they’re all grounded together. Grounding lugs that bolt to the tray to connect to the main building’s ground wire. Even surge protection devices if you’re in an area with a lot of lightning or power spikes. These aren’t just “nice to have”—they’re required by most electrical codes, so don’t skip them.
Wait, what about lighter-duty jobs? Like if you’re in a small office or a retail store where you don’t need heavy industrial gear. We have plastic accessories too—lightweight, cheap, and perfect for low-load trays. Plastic elbows, plastic supports, even plastic splice plates. They don’t hold up to super hot or super corrosive environments, but for indoor, low-stress setups, they work great. No need to spend extra on steel if you don’t have to.
Let me be real with you: I’ve heard so many customers say “I’ll just use whatever random parts I have lying around” to save a few bucks. And then they call me a month later saying their tray system is sagging, cables are getting damaged, or they’re getting electrical shocks. The right accessories aren’t an afterthought—they’re what make your cable tray system actually do what it’s supposed to: keep cables organized, safe, and easy to work with.
Here’s a quick tip when you’re ordering: always measure your tray first. Get the exact width and length of your main tray, then match every accessory to that. If you’re unsure, just shoot us a message—we’ve got a team that’ll help you pick the right stuff, no confusing sales pitches. We can also work with weird, custom spaces too—like if you have a ceiling that’s not straight or a corner that’s at a weird angle, we can hook you up with adjustable elbows or custom-cut tees.
At the end of the day, cable tray systems are only as good as their accessories. The trays themselves might be the main tracks, but it’s the brackets, elbows, glands, and all the little parts that turn a basic track into a functional, safe, long-lasting system. Whether you’re a contractor wiring a new warehouse, a facilities manager updating an office, or a technician setting up a data center, having the right accessories saves you time, money, and headaches down the line.
