Nite Ize Figure 9 Carabiner Rope Tightener-Small

The innovative, patented Figure 9 is a cord tightener that tightens, tensions, and secures cords without using knots. The result is a hassle-free alternative to tying and untying difficult knots and having ropes and cords quickly lose tension. Constructed from strong aluminum and featuring a carabiner clip that attaches to any fixed anchor point, it is the ultimate cord tightening mechanism.
