Aluminum Cord Lock Set - Ultralight Guy Line Tensioners (2 Sizes: 70mm & 37mm, 13.6g)

Tension lines. Bundle gear. Lock secure.

The Aluminum Cord Lock Set is the ultimate ultralight tensioning system that provides precise guy line adjustment and gear bundling in premium 7-series aluminum construction. Featuring two sizes—large 70x49x3mm (10.3g) and small 37x29x3mm (3.3g)—these matte black cord locks deliver reliable rope tensioning for tent guy lines, tarp setups, and gear organization. At just 13.6 grams total weight with CNC-machined aluminum construction, this is the cord lock set that ultralight campers, backpackers, and gear enthusiasts choose when they need precise line adjustment without weight penalty.

Built with 7-series aluminum alloy and precision CNC machining, these cord locks are engineered for reliable tensioning and long-term durability. The 7-series aluminum provides exceptional strength-to-weight ratio—these locks hold tension securely without the weight of steel hardware or the unreliability of plastic alternatives. The large 70mm lock handles tent guy lines, tarp ridge lines, and main support cordage, while the small 37mm lock works perfectly for lighter cordage, gear bundling, and accessory applications. The matte black finish provides corrosion resistance and low-visibility aesthetic that complements outdoor gear. The simple slide-to-lock mechanism allows quick, precise adjustment of line tension—tighten guy lines for storm protection or loosen for ventilation without retying knots. At 10.3g and 3.3g respectively, these locks add negligible weight while providing professional-grade tensioning capability.

This is the aluminum cord lock set that experienced campers use for efficient shelter setup and gear organization. Tension tent guy lines precisely for storm-worthy stability without fumbling with knots in the dark or cold. Adjust tarp ridge lines and support cordage quickly as weather conditions change. Bundle gear and equipment securely with the small locks for organized pack management. Use for clotheslines, bear bag lines, and camp organization tasks. The two-size system addresses different cordage diameters and applications—large for main support lines, small for accessory cordage. The aluminum construction survives years of outdoor use without the corrosion that plagues steel hardware or the failure that cheap plastic locks experience. The matte black finish blends into outdoor environments, and the precision machining ensures smooth, reliable operation. When you need guy line tensioning and gear bundling without weight penalty, this aluminum cord lock set delivers.

Why aluminum cord locks dominate for ultralight camping: Plastic cord locks break and fail under tension, while steel hardware adds unnecessary weight and corrodes. These 7-series aluminum locks provide genuine strength in 13.6-gram total package—the optimal balance of reliability and weight savings. The two-size system addresses different applications without carrying multiple types of hardware. The matte black finish prevents corrosion and provides low-visibility aesthetic. At 10.3g and 3.3g, these locks weigh less than the knots they replace while providing superior adjustability. The CNC-machined construction ensures precise tolerances and smooth operation, and the simple slide-to-lock mechanism works reliably even with cold hands or in darkness. The 7-series aluminum maintains strength through temperature extremes and resists the fatigue that causes cheaper materials to fail.

What Makes It Essential: 7-series aluminum alloy construction, two sizes: large 70x49x3mm (10.3g) and small 37x29x3mm (3.3g), 13.6g total weight, matte black corrosion-resistant finish, CNC-machined precision, slide-to-lock tensioning mechanism, works for tent guy lines, tarp ridge lines, gear bundling, and cordage organization, perfect for ultralight camping, backpacking, tarp camping, bikepacking, and outdoor applications requiring precise line tensioning and gear bundling without weight penalty.

Built For: Ultralight camping and backpacking, tarp camping and shelter setups, bikepacking and adventure cycling, tent guy line tensioning and adjustment, gear organization and bundling, and any outdoor application where aluminum cord locks provide precise, reliable line tensioning and gear management in an ultralight package that eliminates knot-tying and provides quick adjustment capability.
