Single Jacket 1-3/4 handlines.
I have seen a set up of a 300 foot 1-3/4 handline off the rear of an engine. Now, this isn't rubber coated single jacket stuff, but the kind you might see on the wall of a hotel or warehouse. It's stamped 1961 compliant. But it is very thin and light weight.
I'd like to get your opinions/comments on this... and if you use it or not. Let's go one step further... Let's say the local volunteer chief likes it and wants to put it on all engines, vol and carrer. What are your thoughts?

I would not want to use single jacket attack line in a structural operation. Simply way too much stuff in a typical house that can damage the line.
That is part of the reason why every department I have volunteered or worked for had the policy where a single-jacket house standpipe line was replaced with out hose prior to being used. Not only did we not know it's condition, but a non-single jacket line was much more durable and far less likely to fail if moved through debris.
In a wildland situation, or as a brush pre-connect, no problem. But as a structural line, no way.

Don't get too excited too quickly. My favorite hose is very thin and light weight but is still very strong. What is the test pressure stamped on the hose? 400 psi? It is structural attack hose if the test pressure is 400 psi. Some hose like Neidner XL800 has the liner sprayed on the inside instead of heavy rubber. Doesn't last as long but is fantastic to use.

Hi Scott~~
We use " Lightweight" 2.5 for Structural Firefighting, built by a Large Hose Manufacturer. In fact we use this for our Highrise Hose. It is Plastic lined, and passes wonderful every year, in the Annual Hose Test. It weighs considerably less than rubber jacketed hose.. Benefit vs Cost, was a Big Factor, since we all have less FF's these Days, so our FF's work less and get similar results. When weight was an issue, and we looked at 1.75 hose, originally for High Rise, the weight of 75' of Lightweight Hose, was the same as weight as a 4.5 SCBA, or about 14-16# total.
