If you’ve ever spent time coordinating a commercial electrical installation, you know that a trough cable tray project is only as smooth as the prep work that goes into it. As a trough cable tray supplier with 12 years in the game, I’ve seen projects go off the rails because installers skipped a single specialized tool or grabbed a off-the-shelf substitute that just didn’t cut it. Today, I’m breaking down every tool you actually need to get a tray installed safely, accurately, and in line with electrical code—no shortcuts, no last-minute runs to the hardware store. Trough Cable Tray
First, let’s start with the most foundational tool: the manual or electric pipe/strut cutter. Wait, hold on—before you scroll past that, hear me out. Trough cable tray isn’t just plain metal pipe; most of it comes in 10-foot or 20-foot lengths, and you’ll almost always need to cut it to fit around beams, ductwork, or tight corners on site. A lot of installers reach for a hacksaw or angle grinder first, and I get it—those are tools everyone has. But hacksaws leave ragged, burr-edged cuts that can scratch cable jackets, and angle grinders generate so much sparks and debris that you have to stop every five minutes to clear dust and wear a full face shield (even then, sparks can get under your goggles). The right cut here is a battery-powered strut shear or a manual tube notcher. Strut shears, especially the heavy-duty ones designed for galvanized steel, make clean, straight cuts in 10 seconds flat—no burrs, no sparks, no mess. Electric versions are worth the investment if you’re working on a large commercial job (like a 10,000-square-foot retail space or a warehouse expansion), and manual ones work perfectly for smaller, residential-adjacent commercial jobs. I always recommend having at least one of these on your truck, because a mis-cut piece of tray can delay a whole shift.
Next up, a stud finder with depth detection. This isn’t your cheap $10 hardware-store stud finder that only picks up wooden studs. Trough cable tray is heavy—galvanized steel tray can weigh 1 to 2 pounds per linear foot, and add 10 to 20 cables, and you’re looking at 30 to 40 pounds per 10-foot section. Mounting it to drywall, wood studs, or concrete is non-negotiable for safety, and if you drill into a hidden electrical line or plumbing pipe, you’re looking at costly repairs and safety hazards. A depth-detecting stud finder will tell you exactly where your mounting surfaces are, and how deep they are, so you don’t drill through wires. I’ve had customers tell me they skipped this tool and drilled into a gas line on a job—don’t be that person. For concrete installations, a rebar scanner (a more heavy-duty version of a stud finder) is a good backup, because concrete has rebar that can interfere with mounting bolts.
Then, a reliable level. I don’t mean the little 6-inch level for hanging pictures—you need a 4-foot or 6-foot torpedo level, or even a line level for long runs of tray. Trough cable tray has to be sloped correctly, usually 1/4 inch per 10 feet, to keep water from pooling in the bottom of the tray and damaging cables. If it’s not level, water can pool, especially if the tray is run near a door or outside wall that gets exposed to rain. A good level, with dual vials for vertical and horizontal alignment, will make sure your runs are straight and sloped correctly. Pro tip: mark your slope on the wall before mounting any brackets, so you don’t have to adjust the level every 10 feet. I keep a small level in my tool bag and a long one in my truck, because both come in handy at different stages of installation.
Mounting brackets and the hardware to go with them—wait, no, not just any hardware. This is a part where installers often buy the wrong stuff, and I’ve seen trays pull off walls because of it. For most indoor installations, 1/4-inch stainless steel hex bolts and lock washers work, but if you’re mounting to concrete, you need concrete anchors, specifically wedge anchors or sleeve anchors, not the tiny plastic anchors that you use for shelf brackets. For outdoor or industrial installations (like a loading dock or a rooftop), hot-dip galvanized hardware is non-negotiable to prevent rust, which will eat through the bolts in a couple of years. Also, don’t forget the brackets themselves: selectable angle brackets, adjustable wall brackets, and beam clamps if you’re mounting the tray to an overhead beam. As a supplier, I always send a hardware guide with every bulk tray order, but it’s good to double-check that you have the right size before you get to the job.
Once your tray is cut and mounted, you need something to attach the cable ties or bus bars (wait, no—clamps for securing cables, and also, a hole punch or knockout punch? Oh right, cable tray connectors. Trough cable tray sections don’t just butt up against each other—you need to connect them with splice plates and bolts, right? But also, if you need to run a branch of tray off the main line, you need a conduit punch or a knockout punch to make the opening in the side of the tray. A manual knockout punch works for small jobs, but a hydraulic knockout punch is faster for larger projects, because it can punch holes in steel up to 1/8-inch thick in a matter of seconds. Avoid using a drill and a hole saw for this—hole saws can bend the side of the tray, which weakens the structure and makes it harder to attach cables.
Also, don’t overlook personal protective equipment (PPE) that’s specific to cable tray installation. A lot of people think PPE is just generic, but for this job, you need work gloves with grip on the palms, because tray edges are sharp and can cut your hands. Steel-toe boots are a given, but also safety glasses with side shields, because metal shavings and sparks from cutting can fly into your eyes. If you’re working at heights (like on a ladder to mount overhead tray), a fall arrest harness is non-negotiable, per OSHA standards. I always tell my installers (and my customers) that a small cut or an eye injury is not worth rushing a job or skipping a tool.
Wait, let’s circle back to a tool that some people forget: a tape measure with both imperial and metric markings. Even if you work in feet and inches, metric is sometimes used for tray dimensions in certain regions, and it’s way easier to have a tape that has both than to pull out two tapes. I keep a 25-foot tape in my truck, because it’s long enough to measure a whole run of tray without stopping, and it’s durable enough to survive being thrown around on job sites.
Now, let’s talk about what tools you don’t need. A lot of installers bring a whole set of specialty tools that they’ll use once in a blue moon. For example, a plasma cutter for cutting tray is overkill—you’ll just burn the edges and leave a lot of debris that you have to clean up. A miter saw is also not ideal, because tray is often not a 90-degree cut, it’s a compound angle, and a strut shear is better for those cuts.
Here’s a quick story that drives this home: Last year, I had a customer in Chicago call me in a panic. They were installing a trough cable tray system for a new office building, and their crew had used angle grinders to cut all their tray, leading to so many burrs that they spent three extra hours sanding every edge, and they drilled three holes in electrical conduits when they skipped the stud finder. They ended up losing half a day of work, and had to pay an electrician to fix the conduit holes. When I sent them a set of strut shears and depth-detect stud finders, they told me that the next job they did was 20% faster and had zero issues. That’s the difference between having the right tools and cutting corners.
As a trough cable tray supplier, I’ve worked with hundreds of installers and electrical contractors, and the number one mistake I see is not investing in the right tools for the job. A $100 strut shear pays for itself on a single job, because it eliminates the time spent cleaning up burrs and adjusting mis-cut tray. A $50 depth stud finder prevents costly repairs from hidden lines. You don’t need to buy every fancy tool on the market, but these basics are non-negotiable for a successful cable tray installation.
