Landhoow 50 Pcs Emt Pipe Universal Strut Clamps Strut Channel Accessory Electro Galvanized Conduit Clamp with Bolt and Nut, Rigid Pipe Tool

What these clamps are and where they fit

For running 2-inch EMT or rigid conduit along strut, I’ve used a lot of branded hardware over the years. The Landhoow strut clamps are the budget-minded option I tested on a small mechanical room cleanup and an outdoor rack project. This specific kit is the 2-inch size, electro‑galvanized, and ships with matching bolts and nuts for each clamp. They’re meant to secure conduit to standard strut channels or mounting surfaces where a compact, one-bolt clamp is preferred.

These are the classic stamped “universal” style: a saddle that wraps the pipe with a formed hook to engage the strut edge, then a through-hole for the bolt. The simplicity is the appeal—you set, hook, swing over the conduit, and tighten. No complicated multi-piece brackets, nothing proprietary.

Build quality and finish

The clamps are electro‑galvanized steel with a uniform, silver-gray finish. Electro‑galv (sometimes listed as EG) is appropriate for indoor work, dry mechanical rooms, and light outdoor duty where it won’t live in standing water or coastal air. It’s not a substitute for hot‑dip galvanizing or stainless if you need long-term corrosion resistance in harsh environments, but for most residential and light commercial applications, EG is the standard choice and keeps cost and weight down.

Gauge-wise, these are on the thinner side compared to premium brand strut clamps. That’s not a dealbreaker if you install them properly, but it is worth noting. The stamping on my batch was consistent: clean bends, round holes that didn’t fight the bolt, and only minimal burrs. I hit one clamp edge with a file out of habit before sliding it over a painted pipe, but the rest were fine out of the bag. The plating coverage was solid—including around the bend radii—without obvious bare steel peeking through.

Hardware and compatibility

Each clamp came with a bolt and a channel nut. The threads are metric, which matters only if you planned to mix and match with your existing 1/4‑20 hardware. In practice it’s simplest to keep the supplied bolts and nuts together and not blend them into your general bin. The nut profile fit my standard 1‑5/8 inch strut without drama and bit the lips as expected.

If you do a lot of retrofit work in legacy racks with imperial-only hardware, just note the metric threads so you’re not fishing for the wrong socket mid-run. For new builds, it’s a non-issue.

Installation experience

Installation is straightforward:

1) Drop the channel nut into the strut and orient it.
2) Hook the clamp’s tab into the strut lip.
3) Set the conduit in place and swing the clamp over.
4) Insert the bolt and tighten until snug, then give it a controlled bump more.

Because the steel is thinner than premium clamps, over‑torquing is the main way to get into trouble. If you lean on it with a long handle, you can distort the hook or slightly dish the saddle. Using a nut driver or small ratchet and stopping once the conduit doesn’t rotate under hand pressure is the right approach. I treated it like any stamped clamp: snug plus a quarter turn was plenty to hold 2-inch EMT rigidly in place without chewing the strut.

I tried both 2-inch EMT and 2-inch RMC. Fit on EMT was nicely centered with full contact on the saddle. With RMC’s larger OD, the clamp still wrapped without pinching or splaying, but it’s a tighter fit, as it should be. If your pipe coatings are thick, expect a bit more resistance setting the clamp; lubricating the bolt threads (lightly) can help with consistent torque.

Holding power and alignment

Once set, the clamps held conduit alignment across both horizontal and vertical runs. Vibration from adjacent equipment didn’t back the nuts off over a week of observation, and I didn’t need threadlocker. On a ground-mounted rack, I spaced clamps roughly every 5–6 feet and added an extra clamp at vertical transitions. No slippage or chatter showed up after thermal cycling outdoors. Again, these are not structural hangers; they’re for securing conduit to strut, and they do that job competently.

If you’re working on high-vibration installations or where seismic considerations apply, you’ll likely want a thicker-gauge or captive two-bolt clamp from a heavy-duty line. For typical electrical work and solar BOS conduit routing, these are serviceable.

Capacity and project planning

This kit is marketed as a bulk pack. The 50-piece count is appropriate for multi-run jobs, and the per-clamp cost savings versus buying singles at a big-box store adds up quickly. I prefer having surplus on large layouts so I can add a mid-span clamp where a run wants to arc—bulk packs enable that without second-guessing the budget.

Packaging was utilitarian: clamps in a bag, hardware bagged separately. It keeps small parts together and speeds staging. My counts matched the label; I always verify quantities before rolling to site.

Durability over time

Electro‑galvanized hardware will develop surface dulling faster than hot‑dip if it’s consistently wet. After a few rainy weeks on the rack test, there was no red rust or blistering. Indoors, I wouldn’t expect issues. For coastal installs, wastewater plants, or chemical environments, I’d step up to hot‑dip galvanized or stainless clamps—and you’ll pay for that. In the niche that EG is meant for, these are holding their own so far.

The thinner steel brings two implications: they’re lighter and easier to flex during install, and they’re more sensitive to abuse. Don’t pry on them with a big screwdriver to force a misaligned run into place; get the alignment right and let the clamp secure it, not bend it.

Comparisons and trade-offs

• Versus premium strut clamps: The Landhoow pieces are lighter gauge and cost less. Premium clamps feel stiffer and tolerate more torque, and some come in hot‑dip finishes. If you need long-term outdoor durability or are pushing the envelope on spacing/vibration, premium is safer.
• Versus two-piece straps: These install faster and keep the run tight to the strut. Two-piece straps can be gentler on decorative coatings and can distribute load differently but are slower per point.
• Versus spring-nut assemblies with separate cushioned clamps: Cushioned solutions are better for noise isolation and coating protection; they’re also more expensive and bulkier. For standard EMT/RMC, I only spec cushion when noise or galvanic isolation is a requirement.

Tips for best results

• Align first, clamp second. Use the clamp to secure, not to force alignment.
• Snug, don’t crush. Stop once the conduit doesn’t twist by hand.
• Keep metric hardware with its mates. Don’t mix threads in your kit.
• Wipe oil and grit from the strut lips. Clean contact helps the hook seat and reduces the chance of marring the finish.
• If you’re outdoors, consider a dab of anti-seize on the bolt threads to make future service easier.

Value and who it’s for

For electricians, solar installers, and facility techs who need a lot of 2-inch clamps quickly, the value proposition is strong. You trade away some material thickness and brand polish to get a substantial quantity at a lower price per point. For DIYers or small contractors, that’s often the right trade. If your work demands heavier-duty hardware, you already know you’re shopping a different tier.

The bottom line

The Landhoow strut clamps did what I asked of them: secure 2-inch EMT and rigid to strut cleanly, install quickly, and hold alignment without fuss. The electro‑galvanized finish is appropriate for indoor and light outdoor use, the hardware fits standard strut, and the bulk count suits real projects. You give up some stiffness compared to premium clamps, and the metric bolts mean you’ll want to keep this kit’s hardware together. Those aren’t dealbreakers in most scenarios.

Recommendation: I recommend these clamps for residential and light commercial conduit runs where cost, speed, and adequate corrosion resistance matter more than maximum gauge thickness. If you’re building in corrosive environments or need heavy-duty, over-torque-tolerant hardware, step up to hot‑dip galvanized or stainless clamps from a premium line. For everyone else, this bulk kit is a practical, budget-friendly way to get 2-inch conduit neatly onto strut and keep it there.
