If I have an Ethernet cable with RJ-45 connectors crimped on both ends and having no snagless boot protection, what are my options for making the cable snagless after the fact?

Sure, if the RJ-45 connectors were not yet committed to the cable, then I could buy connector boot covers and put them on the cable and then crimp the connectors. But alas, my contractor has crimped 256 cables without providing snagless solution, so now I need to work around it.

Replacing the cables entirely is not an option, as these 256 cables run in the plenum between 20 different rooms.

Re-crimping all 256 cables is also not a great option as this is a horrible amount of less than pleasant work.

The only idea I have so far is to buy the boots, cut them longitudinally with a razor knife, put them around the cable and then glue the cut. But this is also a lot of manual work, although not as bad as recrimping all the connectors. Is there any other well-known solution to this problem?

    "Re-crimping all 256 cables is also not a great option as this is a horrible amount of less than pleasant work." but that is what the contractor is for, not you, right? - "These 256 cables run in the plenum between 20 different rooms." But why have RJ45 connectors on your structured cabling in the first place, rather than patch-panels with RJ-45 on one end and RJ-45 wall-outlets on the other, which can easily last a decade. And then short, flexible , easily replaced patch cables to whatever devices need to be connected?

    why do you need snagless cables in a fixed install location?

    That's a good point, why is the solid conductor plenum cable terminated with an RJ45 connector, instead of a patch panel? Those will be flimsy and problematic.

  • To respond to 3 comments above: cables are crimped with RJ-45 connectors because I invest into feed-through patch panels which allows me to never crimp the cable to a patch panel. This gives me configurability both on front and back sides of the patch panels and does not tie the rack to the building. Yes, it costs more, and I love paying more for a better, more configurable setup. Commented Feb 20 at 11:23

    Yup, and that violates any standard. It's a violation of best practices, which makes your question off-topic. I am an electrician and IT guy and I've learned both jobs from trainee to certified. A patch panel always terminates a wall socket. If you want to overengineer the rack, use a good cabling idea. The newer patch panels click into place, providing a single small socket available for patching, and if needed, you can place them in any direction.

Since nobody has provided any constructive advice aside from attacking irrelevant aspects of the problem, here is the answer that my colleague at work was able to provide: the type of product that solves exactly this problem is called snap-in RJ45 boot (sometimes called "snap on RJ45 boot").
