The Tension Buckle allows you to easily adjust the tightness of your slackline by allowing you to "hold" the line while the tensioning ratchet is released to make room for more line. The beauty of this simplistic piece of equipment is that not only does it allow you to get your line super tight, but it also works as a safety backup to the ratchet.

The heavy duty buckle is rated at over 3,000 lbs and the self equalizing tail insures that the buckle is always centered on your line for easy use. This simple yet extremely effective system is essential for getting long lines really tight.
