We have some great , but once you have a project built, you'll want to enclose it. But how to keep an enclosure weather/waterproof while still attaching cables for power, data or sensors? That's where cable glands come in. By installing these over the cable, they form-fit to make a seal, keeping your project box innards safe from the outdoors.
We have two sizes, and this one, the PG-9 size, which is good for 0.158" - 0.252" diameter. These two are the most common sizes for power & data cables, be sure to measure them so you have the proper fit.
Please check it out for some excellent information about how to use them!
