Will the 3/4" fit over a crimped cat6 cable?

No, it won't. The 1/2" will fit cat6. You could search the ASIN: B07BPRKV6Q or B07NN5JQZH to buy it. Thank you!

Are these accurate sizing?

The product is measured side to side in a flat state. That means the 3/4 size is one half of the circumference. So the circumference is 1 1/2 inches. Doing the math then, the diameter is 0.48 inches. So, 3/4 inch #18057 will fit an object smaller than 0.48 inches. I hope this helps.

Could you make a sampler kit with one of each size heat shrink? It would be great to figure out what size works best.

HEAT SHRINK TUBES ARE SOLD FLAT AND THAT IS HOW THE WRITER KNOWS HOW MANY TIMES THE WORDING IS APPLIED AROUND THE TUBE.... NEEDLESS TO SAY IF YOU HAVE 4 16 GAUGE WIRES YOU WOULD PROBABLY USE A 1/4" HEAT SHRINK TUBE AND ""NOT"" A 3/8 TUBE EVEN THOUGH THE HEAT SHRINK TUBES A SUPPOSED TO BE 3:1 RATIO.........

Will this work with dump labelmanager 280?

Dear customer: So sorry to tell you that our compatible Label Tape replacement for Dymo 18057 heat shrink tubes are not working with the dump labelmanager 280 but only with Rhino 4200, 5000, 5200, 6000, ILP-219, 3M PL200, PL300 and Tyco T107M older machines. I hope it helps you above. Have a good day.
