Self-Adjusting Design: The tent tension springs with double hooks have high toughness and high elasticity, which can effectively tighten and stretch, so that the tent rope is always in a taut state. The tent spring buckle can buffer the wind and prevent the tent from being damaged by the wind.
Easy to Install: The extension spring has hooks on both ends to firmly fix the tent. Connect one end of the spring to the ground bolt and one end to the tent rope.
Widely Used: This camping tent spring buckle can be used for tents, parasol, camping beach tents, sun shade, awning, tarp cover, pool cover, punching bag, hammock, hanging rope, C stand chair, etc. It is very suitable for outdoor camping, travel, picnics, beaches, hiking, fishing, etc.
