WILDKEN Tree Arborist Friction Saver Cambium Saver Loop - Durable

In this review the WILDKEN Tree Arborist Friction Saver is evaluated for climbers who need a reliable, tree-friendly anchor that is simple to retrieve. The bottom line: this cambium saver loop is for arborists and recreational climbers who value durable, lightweight hardware and webbing that protects tree bark while standing up to repeated use. The reviewer found the polyester webbing and hot forged aluminum magnesium alloy rings deliver a strong but low-bulk solution that is easy to carry and straightforward to deploy from the ground.

Key Features

• Material: Polyester webbing and hot forged aluminum magnesium alloy rings provide a balance of light weight and impact resistance so the saver stays durable without heavy bulk.
• Twist control: The wide cambium saver strap limits twisting under load, helping ropes run smoothly and reducing bark damage during work.
• Strength rating: Rated to 22 KN with CE certificate, giving confidence for common arborist anchor uses and rigging tasks.
• Two sizes: Available in 35.4 in or 43 in length so users can select a size that suits their preferred rigging distance and tree diameter.
• Two ring sizes: Comes with large and small rings to aid retrieval from the ground and to provide options for different attachment methods.
• Throw weight: The design includes a throw weight concept to extend range when placing the saver with a retriever ball.

Who It's For

The WILDKEN cambium saver is aimed at arborists, tree care professionals, and serious recreational climbers who need a compact, robust friction saver to protect bark and simplify rope work. Its CE-rated 22 KN strength and durable materials suit typical tree work and make it a practical addition to a climber's kit.

Less suitable for those who require integrated hardware like pulleys or who need an ultralight minimalist setup under very strict weight budgets; also not a substitute for full anchor systems where multiple certified components are specified by a work plan.
