tip covers
Being a telephone systems man, not AT&t or verizon etc..., I go to a lot of businesses to repair their phone systems. At one place where they manufacture cable, I saw hundreds of these little red plastic caps laying all over every where (big plant, 1000's of square feet) picked up about dozen or so off the floor. Man, these things fit perfectly! They were about 2 or 3 inches long, so they covered past the ferrules. They look very similar to what is originaly posted at the beginnig of this post but are longer and red. Looks like the end caps to a role of RG6 cable (RG6 cable is what brings cable tv into your home)
