Friction and Rope Saving Devices

Friction saving devices reduce premature wear on your climbing line and eliminate damage to tree limbs caused by the climbing line running over a branch. We have a wide selection of friction saving devices, like the popular Buckingham rings, the classic Leather cambium saver, and more versatile solutions like the ART snakeanchor, the pullySaver, and the in-house Vortex AFS (adjustable friction saver).

Buckingham Friction Savers with Aluminum Rings

24” / 2’ Friction Saver
36” / 3’ Friction Saver
48” / 4’ Friction Saver
60” / 5’ Friction Saver
72” / 6’ Friction Saver

Friction savers offer minimal friction when working from different positions in the tree and can be wrapped around a stem for use as a false crotch where no natural crotch exists to run the line over. Friction savers also aid in keeping the slack out of your climbing line for added safety during your ascent. Buckingham friction savers are available with your choice of steel or aluminum rings (steel rings are stronger but aluminum rings are lighter and dissipate heat better.) The rings are of different sizes to aid retrieval of the friction saver from the ground. The strap is reinforced and stitched nylon webbing. Friction savers are available from 24” to 72” in length. Click here for Buckingham friction saver installation instructions.

Buckingham Friction Savers with Steel Rings

24” / 2’ Friction Saver
36” / 3’ Friction Saver
48” / 4’ Friction Saver
60” / 5’ Friction Saver
72” / 6’ Friction Saver

Friction savers with steel rings work just like those above, but with greater durability (and weight).

Ball w/cord
equaLIZA Link

The pulleySAVER is a system for saving friction on ropes, which can be used in many configurations and greatly aids working the tree. The attachment as anchor point on a tree can be implemented in four different configurations, depending on the specific application: as swinging element in a double leg configuration, as chock hitch, wound around in a double leg configuration, or narrowed in a double leg configuration. Easily retrieved from the ground. The equalLIZA link (sold separately) is a short sewn rope on a DMM ring meant to be used as an equalizing link if the pulleySAVER is used on two anchor points.

Vortex AFS (Adjustable Friction Saver)

Can be set and retrieved from the ground like any ring and ring saver, and includes retrieval ball.

Mystery Rope Saver

Mystery Rope Saver

42" / 3.5' Saver
72" / 6' Saver

The Mystery Saver is a way to save a bit of money on a top-quality ring and ring style rope friction saver. The professional rope splicers at Iron Street sew these friction savers out of remnants of top-quality arborist rope left over from making the professional rope tools you see sold at WesSpur. What that means is you get to save a few bucks on a brand new rope friction saver and we maximize efficiency and produce less waste. Everyone wins!

Each Mystery Rope Saver is constructed from an arborist line a sewn spliced strength of at least 5,400 lb, and a minimum diameter of 11mm / 7/16". Rings are aluminum climbing rings.

*The ropes used to make these friction savers will vary. Special requests for rope, or rope color may not be made for this item (though custom friction savers can be made to your specifications.)

These items are only available when shown as in-stock, and may not be back-ordered.

Rope Sleeve

Dan House Rope Sleeves

3/4” Inner Diameter x 30”
3/4” Inner Diameter x 60”

Constructed from flexible metal conduit covered in heavy vinyl. Slick metal interior drastically reduces friction and rope wear, while the jacket grabs the bark to keep the Rope Sleeve in place. An orange band at the halfway point helps center the rope sleeve over the limb. These rugged rope sleeves are easily mended with vinyl tape, and come with a two-year replacement warranty. To install the sleeve over the limb you hoist it up while on your climbing rope with a slippery hitch. Once positioned and centered you pull and pop the slippery hitch out. Minimum safe bend diameter is 6" for the 3/4" ID (inner diameter) sleeve.

The Snakeanchor is made from doubled cord which is stitched together with openings every 2.7 inch so that a carabiner can be inserted at any point along the length, making it adjustable based on which point you use. ART has used doubled 8mm cord to give the Snakeanchor a wider surface area for better grip and abrasion resistance. An aluminum ring protects the eye at one end. WLL on the Snakeanchor is 2 kN. Available in 8' or 16' lengths.

ART Rope Guide 2010

ART Rope Guide 2010 with Cocoon

5’ Ropeguide
cli225 Special Order Item
10’ Ropeguide
cli218 Special Order Item

Smooth rope work and special care for the cambium join forces in this outstanding device. The Rope Guide 2010 is very light, and ropes run effortlessly in it. The Rope Guide must be set by hand, but may be retrieved remotely (this is greatly aided with the Double Snapper). The new ring is 50% lighter than a solid ring and still achieves comparable stability as well as much enhanced safety. The rope now runs protected within the tube-shaped ring - and it might sound strange but it is true: the rope enhances the breaking strength of the ring and vice versa! The contact surface is 8 mm parallel sewn double rope makes which combines the strength and advantages of rope with a wider contact surface.

Right behind the tube shaped ring there is now a small "fender" built in. The fender allows for the ring to align vertically when pulled from a forked branch, which makes for an easy gliding even through smaller forks. Release lever: The longer lever now allows for an easy release of the locking cam when pulled, as with the Positioner 2. This makes retrieving even easier and more reliable. Spring loaded cam: This feature prevents rope from accidental sliding.

ART Ropeguide Twinline

ART Ropeguide TwinLine

Ropeguide TwinLine
15' Splice Anchor for TwinLine
Stoppergate for ART TwinLine

The RopeGuide TwinLine are two lines: Either a short, spliced ART rope (SpliceAnchor) with open eye in different lengths (up to 4,5 m) or a long rope according to EN 1891 (10 to 12 mm diameter) without termination in any lengths can be used as anchoring rope. The short rope system is well-tried.

With the long rope system, it is now possible to install the RopeGuide from the ground very easily. With one work step two rope lines can be installed to the anchor point. It is possible to use both Single or Doubled Rope Technique for ascent.

The long anchoring rope can be used as second, fully reliable ascent rope because of the removable knot shell made of high-tensile plastic (patent pending). So it is possible for a second person to ascent at the same time as the first climber or to follow the first climber, e. g. for rescue.

Certified to EN 795 B (temporary anchor), CEN/TS 16415:2013 (can be used simultaneously by two persons ) and in accordance with EN 355:2002 (Energy absorber).

The StopperGate is nessecary for using the the RopeGuideTwinLine and RopeGuide 2010 in the SRT-Setup. It provides the trapeze to be crushed be the Cocoon. In the SRT-Setup the stationary rope is running through the Cocoon and the Trapeze. Behind an alpine butterfly knot follows, that not slips through the Cocoon and Trapeze. The StopperGate is clicked directly on the Trapeze.

The rope guide splice anchor is a 12mm, spliced rope to be used as a friction saver rope with the Ropeguide TiwnLine.
