Adhesive for Electrical Cord Entering a Fixture

[cloves]

Hi all,
I was wondering if anyone had thoughts on what adhesive would work best to keep a cord from slipping out. I want something flexible. Tried simple glue gun as a temp fix, I knew it was'nt going to hold up. I think this is called a strain relief but not sure. I already took this apart and pulled the jacket back in its just not holding, cheap **** jacket isn't thick and slips out.

I bet the jacket was cut back way too far, there is too much stripped wire on the other side. Take it apart, shorten the wires, and reclamp.

an oeteker 2 ear clamp ( of the appropriate size) on the back side would help keep it from pulling out too

Used to tie a knot. Not sure what is best.

Is this the original cord?

I'd replace the cord or get a new fitting. Cheap on Amazon

 

[PCustoms]

I bought a couple sizes of these for an LRD relay and the seemed to work and hold up

If you have access to the inside, a zip tie around the insulation will work. As mentioned a knot will of course work, but if you are limited in space, a thin zip tie is your friend.

Hog ring inside. It looks like you could do that by removing the compression grommet fitting, I usually use a backer washer.

Thanks fellas, some great ideas. I can open them up and tie the jacket off. Good thinking zip or hog tie.
Btw , yes these are the original power wires.

Use quality cord grip, not some lousy **** from China & install per instructions that way no site hacks are required

Open it up and pull the jacket back in. The just put a couple of zip ties around it and pull them really tight.

What is it anyway ?

Keep in mind that if it’s willing to pull out from the fitting. It’s also willing to push up into the device. Potential short circuit.

Don't follow the example of **** sent to us from China!

You can do this right by tying an Underwriter's knot: https://en.wikipedia.org/wiki/Underwriter's_knot

No, its just from me setting up these lights for events and then quickly circle wrapping the cords. The bushing that holds them in just never held them in.

Thanks @wssix66 I see what the previous poster mentioned by a knot now. Its an underwriters knot.

I'm glad we have so much experience on this site. It's like a manly online garage lol.

Get a proper cord-grip. If for some reason you can’t find one there is another way. Disconnect the wires and pull that end off. Wrap the cable with electrical tape until it’s thick enough for the grommet to hold it in place.

That "bushing" (grommet) was never meant to hold wires in place. It's really just a seal to keep stuff out. A cord grip clamps down on the cord when tightened. That's what you are after.

These probably would need a new hole drilled, but they will definitely hold.

 

[BreeStephany]

If the cords commonly get pulled on during repeated setup / takedown as @cloves suggests, I would look into replacing your cord grips with wire mesh strain reliefs! The tighter you pull on the cable, the harder the wire mesh grips the cable.

We commonly use these for overhead cable drops and they never let go of the cables.

A decent Legrand BOX30 or equivalent is very inexpensive at around $10~$15 a grip.

Just my two cents.

 

[tool_scrounge]

I use cord grips all the time on projects and never have cord pull out issues. But I am buying quality and correctly sized cord grips from Digikey and using quality SO cable. I can see possibly having an issue with cables with hard slick plastic jackets though.

You can try it out on scrap wire before and play with it. The knot is amazing in what it can do. Its a little challenging tying it for the first time. This site can help: https://www.animatedknots.com/underwriters-knot

It's still good to have a good secondary strain relief on the outside of the fixture that grips the sheath. This will keep the sheath from pulling out with the inner core staying in place. The underwriters knot will insure that no strain makes it to the electrical contacts, causing a short or disconnect. (There should be a little slack between the underwriters knot and the internal contacts.)

That appears to be an outdoor rated led light. That's likely just a rubber bushing inside. Take the whole fitting off the housing and replace with a regular cable gland.

I've had these for over 30 years in use and never a problem.
