ISC Port-a-wrap

Does anybody have any experience with the small version of this? I'm wondering if having a 14mm rigging rope would make a big difference. It says only 12mm for max size on this device. I'm just looking for a small light lowering device and don't want to spend the cash on the Stein model or have the weight of the medium port-a-wrap. My rigging line is 9/16" and I'd rather not downsize Just curious what you think. I have used a medium porty for years and years but this is some personal gear for me for light rigging scenarios. For heavy duty stuff I'll switch over to the company gear and the porty we have. .
 
i think it depends on the make up of the rope. sampson double braid gets a little swollen as it ages, so it doesnt run so smooth. but sterling Atlas 14mm rigging line works fine.
 
I agree I love mine for light stuff. There is also another device I can't think of the name of that is used above the load. Square tube, side plates and pins to separate line...I like that alot when I am in the tree also. Some will know the name, I was turned on to it here.
 
That's a BMS Belay Spool

There are threads in the archive about it. Look up "OLDS" overhead lowering device system. It wouldn't work very well at the base of a tree unless
The rope
Went through a redirect and it was run in horizontal
 
That's what I have. I was given a 120' of new atlas 9/16 rigging line and was thinking of using the ISC for my own gear. We only have 1 portu and usually have 2 climbers up at a time. The only solution to my own liability is to use my own stuff. The other climbers don't worry about the condition of the gear the have to use. I'm a little more conservative. I suppose I'm like a contract climber working for 1 company exclusively but I basically provide all my own gear and saws. My tool box is packed and I don't have much more room for gear. I figured that little ISC would fit the bill but I don't want to buy a smaller rigging rope for someone else's company. Thus the question can I use a rope bigger than it's rated for. Thanks guys.

Yes. I got it and it runs fine. The only issue with it is user error. So I had a good sized maple limb ricced off. Told the rope man exactly how to set it up and so did the foreman. Cut the limb, rope flew out of the device. Limb on the deck and a rope smack in my no no bikini spot. I'm glad it was only a glancing blow and not a bulls eye on my left fella. I took a few minute break and may have said some unprofessional things. He didn't rope again yesterday and nothing went wrong.

Oh man! I'm guessing the roper put the bight behind the L-pin rather than in front, allowing it to pop completely out? There also must have been no more than one round turn after the bight? I don't know...just glad you weren't hurt worse.

That device was invented by Dave spencer and Lorne eide.

Canadians might know Dave as the runner up on the first season of 'Canada's biggest know it all'

If that is in fact the one I posted a picture of, Dave Spencer DID NOT invent it.
Attached is a picture of the 1st Porty 1 (low left - yellow); 1st Porty 2 (top right - yellow, next to a large Porty 3) crude, but effective; 2nd generation of the Porty 2 (low right - orange).
And, I have years of experience using them all.
