Yes, adjustability (as easy as possible) is the key. The end user needs to have the ability to make the rope longer or shorter for 1 - 2 centimetres. The problem is that there is no space for a long bury, it can't be more then 7 - 8 cm. @Brocky suggested that at the weak spot, where the tail exits at the bottom, the strength would be reduced by about 20% due to sudden change in diameter. That means that the rope would still have breaking strength of about 760 kg. I think this should be good enough for the application used, but only testing will show.

Yes, sorry, 950 daN (kg) . Unfortunately I do not have the tools to measure the breaking strength, but might improvise with something just to see where it breaks first.

Locked brummels would make a difficult job to adjust the length of the rope. In my current version this is quite easy, just release the lock and the loop can be adjusted. The rope is part of a sports training tool so this feature to adjust the length of the rope quickly is important. What would be the estimation, how much is Dyneema rope weakened by such a sudden change of diameter (where the tail exits)? I am using 3 mm Dyneema (950 KN) so there should be quite some reserve regarding breaking strength for what I am using it. Hopefully this weak point is not reducing its strength too much--tests should show.

Yes, the "lock" passes through both of them. Your estimation makes sense.

Hello, I have a situation where I need to splice Dyneema rope, however there is not enough space for a long enough splice. Therefore I created a "lock" as seen on the picture below. If you release the lock you can easily adjust the length of the loop and consequently the length of the rope. Would such a lock significantly weaken the rope strength and/or durability? Any input would be appreciated... Imgur IMGUR.COM Post with 0 votes and 2 views.
