Bring some serious '90s action-sports energy into the canopy with the Rocket Power Lanyard Kit.

Everything you need to get rigged and get climbing — curated by Bartlett Arborist Supply.

Rocket Line — 7/16" Arborist Positioning Lanyard

Rocket Line is a 7/16-inch (11 mm) double braid arborist climbing rope with a 5,670 lb minimum breaking strength, built for tree climbers who need a rope that stays round, runs smooth, and stays visible in heavy foliage. Pair it with your favorite hitch or mechanical rope grab to create a premium adjustable lanyard.

Built With a Triple-Layer Construction

Rocket Line combines three layers of engineered polyester:

• 24-strand polyester cover — a tightly braided jacket that delivers a smooth, broken-in feel right out of the bag and excellent grip in hand
• 16-strand polyester core — the load-bearing interior that gives Rocket Line its strength and durability
• 3-strand neon green twisted second core — a unique inner core that keeps the rope firm and round when loaded, so it won't flatten in mechanical devices or under your hitch

Why Climbers Choose Rocket Line

Stays round under load. The additional twisted second core prevents the rope from going flat when weighted — meaning consistent performance in hitches, mechanical rope grabs, and friction devices.

Easy to spot in the canopy. Hi-visibility colors make Rocket Line easy to track while climbing in trees with dense foliage — a real safety advantage when you need to locate your line fast.

Smooth in-hand feel. The 24-strand polyester cover runs clean through your hands and your hardware, reducing fatigue on long climbs.

Pair Rocket Line with your favorite friction hitch or mechanical rope grab to create a reliable adjustable lanyard.
