Caianwin 20-Pack M20 Cable Glands (IP68, PA66 nylon) for M20 cable glands
Product description
What it is and why people buy it
These Caianwin 20-pack M20 cable glands are compression glands for use on electrical boxes and enclosures where you want a cable entry that’s more protected than a basic, open knock-out. The pitch here is pretty straightforward: you push the cable through the gland, feed it into the cable entry point, then tighten the locking nut. It’s the kind of accessory that tends to get added after you’ve already planned the wiring route, because it helps keep the installation tidy and better sealed.
On paper, they’re aimed at outdoorsy or damp-condition setups thanks to the IP68 waterproof rating. The pack includes 20 pieces, which makes it more appealing if you’re doing more than one enclosure or you like having spares during a job.
Key points to consider before you choose
The most important thing isn’t the “20-pack” fact—it’s getting the thread and cable range right. These are M20 glands with an M20 x 1.5 mm thread. The stated cable diameter range they suit is 7–11 mm. If your cable falls outside that, the gland may not grip properly, and you’ll be left troubleshooting rather than finishing.
You also get a material note: PA66 plastic with properties described as flame-retardant, waterproof, and “degradable”. That combo reads like a safety- and durability-focused plastic for typical junction boxes, switches, distribution boxes and wall-mounted enclosures, but do bear in mind you’re still choosing plastic rather than metal if your setup demands higher mechanical toughness.
And yes, IP68 implies strong water resistance, including during rainy seasons—just don’t treat any cable gland as a magic seal if the rest of the enclosure isn’t properly assembled or sealed.
Where it shines in everyday installation
The good news is that the workflow matches what installers expect: cable gland in the cable entry, then tighten the closing nut. For a practical example, imagine wiring a wall-mounted distribution box outside—once the cables are routed through the box entry points, these glands help you lock them down cleanly and reduce the chance of water ingress at the entry.
Because it’s sold as a multi-pack, it suits projects like: - multiple cable entry points on one enclosure, or - multiple similar enclosures (workshops, outbuildings, garden lighting feed points)
It’s also the sort of item that often ends up being “worth having” in the spares drawer for future maintenance, especially if you regularly deal with junction boxes and switch boxes.
The less convincing parts (what to watch)
This isn’t a universal gland for every cable and every box. If your enclosure needs a different thread size, or your cable diameter isn’t within 7–11 mm, you’ll have to look elsewhere. That mismatch risk is probably the biggest limitation.
Also, the description mentions there are different sizes available, so you should verify you’re selecting the right M20 variant for your specific cable entries. Lastly, while the plastic is described as flame-retardant and waterproof, you still need to consider the broader setup—gland sealing works best when the enclosure and cable installation are done correctly.

Who it’s for (and who should skip it)
It makes sense if you’re fitting or maintaining electrical boxes—especially wall-mounted distribution boxes, junction boxes, switch and socket style enclosures—where you want a more water-resistant cable entry and you’re working with M20 cable glands.
It may not suit you if you need a different thread size, if your cable diameter sits outside 7–11 mm, or if you’re specifically chasing a more heavy-duty mechanical solution where metal glands are usually preferred.
Should you buy it?
Worth buying if you have M20 x 1.5 mm cable entries, your cables are in the 7–11 mm range, and you want an IP68-rated gland for weather-relevant installs (rainy-season type conditions). The 20-pack is also a practical choice when you’re doing multiple entry points or multiple boxes.
You may want to skip it if compatibility is uncertain—especially the thread and cable diameter—because those are the two factors most likely to cause a poor fit. If your project is a one-off and you only need a couple of glands, the pack size might feel like overkill too.
Mini FAQ
Questions people usually ask
Q: Are these suitable for outdoor or wet locations? They’re described as IP68 waterproof, including performance during rainy seasons, which is the main reason people choose this style for outdoor or damp setups.
Q: What cable diameter do they fit? The stated diameter range is 7–11 mm.
Q: What thread size is it? It’s an M20 x 1.5 mm thread.
Q: How do you install them? The basic method described is to connect the cable to the cable entry point using the gland, then tighten the closing nut.
Q: Is it only for junction boxes? No—based on the description, it’s used for plug and switch applications, distribution panels, switching panels, and cable fixing points in general, wherever cable entries need a sealed compression gland.
