20PCS Electric Cable Protection Cord Buckle Black Wire Cover Round Nylon Cable Strain Relief Bushing Wire Strain Relief Bush Cord Grommet 6N-4 4N-4

good

Great item works as described

Dimension "C" for the 6N-4 was stated to be 4.2mm. It turned out to be 2mm. The wall thickness of my cabinet is 2.5mm so fitting the bushing requires modification. If the product description had been accurate I would have done a little more research before buying this item. Unfortunately, most of the product listings on Amazon don't even specify these dimensions so we're shooting in the dark.

Worked well as expected, nice assortment.

These are made with good grade plastic and the joining tether is tough so you will not lose one of the halves. There is not a hole drilling guide included, so I had to look it up online. The recommended 1/2" diameter hole for a 4N-4 strain relief seemed too loose when tested without a cord, but the 15/32" hole I initially drilled proved too small with a flat 18/2 cord. Even 1/2" was a challenge, but made for a good, tight connection.

no issues with the product. does what it says. just took a star off because i hate these things. imo, there are much better ways to accomplish strain relief. BUT, this was what i needed for a project, so i had to get them. and they worked perfectly as intended.

Not much to go wrong. Pretty simple to use.
