    What Mr Ed says.... You may find yourself in the dirt my friend. There are enormous forces at work when you get in a hammock. I'm sure someone knows the maths but it's something like every kilo of downforce is multiplied by the distance between points of suspension..

    Look at the pic below. Your Karabiner should be stamped with a weight rating in Kilo newtons (Kn). If there are no markings or they have "not for climbing" stamped on. I'd be more likely to kepp your keys on them or use them as gear clips under your tarp.
    For every kn of pressure, it may hold 225 lbs of weight? So for instance, if you had a caribiner, that was rated at 25 kn. Could it hold an inanimate object that weighs roughly 5500 lbs

    Dave, it was one mistake that has cascaded and the person in question has tried to explain.

    As the others have said though thanks for the heads up on ScrewFix.

    Unfortunately it would cost me more to get to the nearest ScrewFix than it would to actually buy 15 from alpkit and have them delivered as the delivery is in with the cost.

    That was my reason for posting the link in the post above yours.

    Hi Leon

    Just what I was looking for mate.

    I have 6 packs of the small ones on order. They will be used in my parachute system to do away with guy lines leading down to the ground.

    Cheers

    i'd still say get some decent Karabina's for your Tarp, remember if a sharp wind comes through the weight load on your tarp is going to increase a fair amount, even more so if its raining

    I have used these on my tarp all year round for at least the last 2 years and "touch wood" I haven't had a problem with them yet. If you have concerns then use two of them back to back (so the gates face in opposite directions) as you would with snapgates to make them more secure. With this method you get the extra strength but you still keep both the size and weight down to a minimum.

    Hi Leon,

    Screwfix also deliver. You can find them here: www.screwfix.co.uk. I haven't checked to see how their delivery costs compare to Alpkit's.

    FYI, I have also used the Alpkit version on my tarp with no problems.

    Cheers!

    Hi Huon, dave mentioned the postage in his initial post.

    This means that for £7.50 delivered I can get 15 from Alpkit or 10 from Screwfix for £7.95 delivered.

    It may work out better with higher quantities, perhaps on a group buy where a lot of them are being bought and possibly talking to screwfix to see at what level / quantity they will give a discount for higher amounts / numbers.

    The only problem that I then see is the redistrobution. So to make it viable would be arrange a meet and ask the members of the meet who would like to be in on a group buy and see whether it's worth it.

    If folks were interested in this I'd be happy to sort out purchasing the screwfix ones. I've got a shop 5 minutes from me so it wouldn't be any trouble to pop along and buy them and then post on. I'm pretty sure I could beat their P&P.

    That's a generous offer Steve and people would be daft not to take you up on it if they are in need of these.

    Went and bought a pack for myself and they're not too bad. Weigh in at about 9grm each and are probably a lot stronger than their equivelant size in aluminium.

    If folks do want some I can do the M4 size for £3.90 per pack of 10 including P&P 2 packs for £7.00. Just drop me a PM
