Muzata 300Pack Black Cable Railing Rubber Grommets for Metal Post CB28

These grommets are sturdy - made from quality material. They are a bit thinner than the off-brand, but the center hole is slightly larger.

Very great product looks better than the metal ones with the adhesive tape in my opinion, I like the rubber ones better than the metal ones and a lot less cheaper and it looks good.

These worked perfect for every hole except the terminating holes. Easy to install and remove if needed. Just be careful if you're prepping the posts, they are also easy to push all the way through the hole and fall to the bottom, where it's difficult to recover. Ask me how I know...

Works great. Using with black cable, looks awesome.

These did what they were supposed to, but kept popping out and took a lot of work it get them all in and stay in.

I love these rubber sleeves, very easy to use and so great for protecting your cable while increasing aesthetics. I used a 3/8" bit to drill in extruded aluminum and these fit perfectly. You'll need to push them in on side at a time and you will 100% need access to the back to get them to sit flush. They require you to pull the backside flush, the little flange that holds them tight in the hole. The rubber feels high quality and I expect them to last a very long time.

I'm very pleased with these. They pop into place and fit 3/8" holes perfectly. The feel like they will last.

Works as intended.

These worked perfectly
