anti-slippage knot

tie-off

Put the folded tail coming out of the seaHorse in between 

the BackPin and the HollowCenterDiverter. Make sure that 

the webbing is straight and not twisted.

Pull through enough webbing to wrap around the sea-

Horse and the tie-off later. Make sure that the line is tight 

against the HollowCenterDiverter.

English

With low tension slacklines (common in highlines) micro slippage might occur. This means the webbing slips millimeter by 

millimeter out of the weblock. This is not a malfunction, but a consequence of how the weblock is build. The anti-slippage 

knot and the tie-off demonstrates in the video and this manual completely stops this micro slippage on most lines. With very 

slippery webbing it’s at least minimized and will be stopped when the tie-off is tensioned. Most important the anti-slippage 

knot prevents any tail misalignment caused by slippage of the weblock. Tail misalignment by tail-walking could lead to 

complete failure of locking the webbing. 

Be sure to always tie-off your weblock/webbing so that your line will always stay connected to the anchor point.

More information about micro slippage and 

tail-walking and the tutorial “How to tie-off the 

seaHorse” can be found in this video.

4. Anti-slippage knot & tie-off

4.1

4.2

Wrap the tail of the webbing around the seaHorse (in be-

tween the FrontPin and the HollowCenterDiverter). 
Which direction to wrap around doesn’t matter.

4.3

Now put the tail of the webbing into the Hollow-

CenterDiverter in a way that the webbings are 

crossing once. 

4.4

Pull the knot tight around the seaHorse. Make sure the webbing is 

nicely on top of one another and not twisted.

4.5

You can tie-off the seaHorse in multiple 

ways (for example A+B). 

4.6

Back-up option A

Back-up option B

Take the webbing coming out of the HollowCenterDiverter and the other end 

of the webbing coming from the seaHorse and pass them both around the 

anchor point. Tie them together with an appropriate knot (for example: Double 

Fishermans knot). Make sure the tie-off is a relatively tight. The benefit of this 

backup is that no extra material is needed.

Make a Figure-8-knot (or double fig. 8) with the webbing coming out of the 

HollowCenterDiverter and connect it with an additional carabiner or shackle 

to a separate sling/anchorpoint. 
The benefit of this tie-off is that it is easy to check and easy to tie.

Do not forget!

Before you release the softRelease, untie your tie-off.
