14.00 142.00

The seaHorse is the world’s first ISA 51 certified HighTech Highline Weblock. Made from a single piece of aluminium, has a versatile HollowCenterDiverter and a excellent PreTension-Ability. This WebLock also impresses with its low weight and, at the same time, the generous dimensioning, which allows comfortable handling (even with up to 8mm thick slackline webbing).

seaHorse 1.5: the best pretension-ability weblock with Double-Pin

isa approved highline aproved weblocker
ISA Certificate

According to ISA 51 Standard, the SLACKTIVITY seaHorse is a tested and certified highline double-pin weblock

The seaHorse is the most sophisticated weblock on the market, it can be used with 25mm and 20mm webbings (with spacers). The new design adds versatility, new functions, and low weight. The seaHorse is forged from a single piece of aircraft aluminium, which allows it to be really strong and lightweight.

The biggest innovation is the hollow center diverter which allows a variety of soft connections. This can be really useful when building a HangOver pulley system, attaching a regular pulley system, or attaching a rope to train for highlines in the park. We even built in some grooves that keep your soft attachments in place instead of sliding up. Note: the hollow center diverter cannot be used to anchor the seahorse.

The geometry of the SLACKTIVITY seaHorse is optimized for the most efficient pretension possible. A lot of testing with a big modular plate has led to the perfect dimensions for a HangOver pulley system. To see how to create the lightest 15:1 system on the market, you can watch the video above!

The two pins are connected with a rubber connection cord which is less likely to get entangled around the pins while tensioning the line.

    By far my favourite weblock. Is super easy to pre-tension and to make the anti slipping knot (because of the hole in the middle). It works great with tick soft-realeses.

    Es una banana muy bien construida, y muy suave para tensar. Sin duda la volvería a comprar.

    Very good webblock : it’s easy to feed the slack through it and you can also connect a soft-released to it (for a cleaner rig).

    I absolutely love this weblock. It is so light and having the center diverter makes both tensioning and tying off tails a breeze. From the friction divots to the hooks you can tell that this was designed by people that love slacklining. I would highly recommend.
