Great workability

  • Familiarity: I've put it through the wringer

7mm makes great anchors. Never tested in icy/wet conditions, but for general purpose use it's not stiff like the other many alternatives out there. Since it's so soft, I'm not sure how it will hold up in terms of durability but it's plenty stiff enough to undo knots.

From storing my rack to using as Prusik's. Love this stuff.

BOMBER CORD

  • Familiarity: I've put it through the wringer

This is great accessory cord, the price is spot on, iv made multiple slings and aiders with this stuff. Making anchors with this cord is great, thing knots are super easy and the sheath seems to uphold great

Great for prusiks

  • Familiarity: I've put it through the wringer

6mm accessory cord is the smallest typically rated for life safety applications, so I never use anything below that (excepting Kevlar, spectra, dyneema, etc tech cords).

6mm is just about perfect for prusik use on typical 9.8mm dynamic climbing rope. I typically keep a very small loop on my harness at all times for rap backup or rescue use.

Since 6mm cord is small enough to not be too heavy or bulky it is also great to use as a chalk bag belt or nut tool wrap/tether. Lots of small ideas like that so that you can always have some spare cord with you in a pinch.

7mm works well for cordellette/equallette use. 20ft is generally the recommendation I have seen. I take a bit more in case I need to leave some behind to beef up an anchor or whatever.

I have bought a great deal of this before, likely to buy more in the future.

Great for Top Rope Anchors

  • Familiarity: I've used it once or twice and have initial impressions

I help run a high school outdoors club. I am just starting to use this cordelette for setting up top rope climbing anchors. The 7 mm works well and the 50 feet gives me plenty of real estate to tie off on multiple points. I am already thinking of getting a second one so I can set up multiple climbs. I really like it so far.

Improved way to tie

Here is a nifty, quick and easy way to use your cordelette that I found. Enjoy.

Cordelette and Cornice Cutter

  • Familiarity: I've used it several times

I use the 6 and 7mm for making cordelette's and the 4mm for a bomber cornice cutter that I keep in my backcountry ski pack. Ratings have been discussed in detail below. make sure to check those out to get the correct size for your needed purpose.

Accessories

  • Familiarity: I've used it once or twice and have initial impressions

Here's my rule of thumb for cordelette and prusik, of course always use your own best judgment depending on the situation. For single point attachments always use climbing rope and 24kn anchors. But for multipoint anchors, unless you're top-roping from an overhanging tree trunk, you will need at least three other anchor points to feel safe. With an equalized load at 3 anchor points use 8knx3 aggregate and that is why checking the specs, Sterling accessory cord 6-7mm is more than adequate for cordelette with multiple anchors. For use as prusik just keep in mind that your harness is still tied to the rope and that by keeping your pro reasonably taut there shouldn't be any problem even if the prusik slips on 5mm cord. But if you are weighing in at over 200lbs use whatever you feel comfortable with and if 7mm prusik is too slippery or stretchy, in that case 8mm might be the way to go.

Good multipurpose cord

  • Familiarity: I've used it once or twice and have initial impressions

I used the 6mm cord for making a prusik and it worked well. No complaints. Seems like good, strong cord that I can use for a variety of things.

Very Impressed!

  • Familiarity: I've used it once or twice and have initial impressions

I bought this cord to use for a bear hang. We lifted 4 packs over and over for 3 days and this cord took the abuse like a champ. Still looks brand new and it is amazingly strong for a 6mm cord.

Great accessory cord for backpacking

  • Familiarity: I've used it several times

I picked up 50' of 4mm cord for bear bags, tarps, etc when backpacking. If you have a smaller group or a shorter trip, 4mm cord is a bit overkill and you can get away with a lighter option, but 4mm is a great size for bear hangs with lots of food (group of 4 out for 5+ days). It's not quite as brutal on the hands as a 2.5 or 3mm cord would be. I wouldn't use the 4mm size for any climbing applications - make sure you pay attention to the strength ratings for each diameter.

The website is not super clear about the ratings, so this is all the accessory cord strength ratings by diameter.

Got 5mm for friction knots

I think it is exactly what I am looking for. No complaints other that I with I could pick the color ;p

Strength by diameter from sterling

2mm- 225 (1.0kN)
3mm- 472 (2.1kN)
4mm- 1,034 (4.6kN)
5mm- 1,169 (5.2kN)
6mm- 1,978 (8.8kN)
7mm- 2,788 (12.4kN)

This shows all the sizes sterling offers and not just the ones on Backcountry.

I am looking to get some to extend anchors...

I am looking to get some to extend anchors over an edge and also for prusiks. What diameter/s should I get?

Best Answer Responded on

These cords are NOT intended for climbing anchors. Especially for the rigors of a top-rope anchor (where the anchor cord will see repetitive wear in a concentrated location and where there is little visual inspection of the anchor while in use) I would NEVER use this cord for that purpose.

For prussic loops either the 6mm or the 5mm would be fine. Use the 5mm only if the rope you are prussicing onto is less than 9mm... the 5mm cord will bite better on these thin ropes, but on ropes thick enough, I recommend taking advantage of the extra strength of the 6mm.

The strength rating on this page should not be trusted. Sterling's datasheet shows the 6mm cord having a MBS of 8.8kN and the 5mm MBS of 5.2kN.

For anchor building look into Sterling's PowerCord. Its much much stronger (20kN) and intended for these purposes. Webbing is another common and very cheap option for anchors, but webbing requires some special attention in knot tying.

Hope that helps - have fun and be safe!

PS. just to show what I mean:
The 6mm cord: http://www.sterlingrope.com/product/458868/A060/_/6mm_Accessory_Cord
Sterling's product page for "Cordelettes" (intended for anchor building) only shows the 7mm cord (12kN) and the PowerCord (20kN).

7mm or greater for anchors.

General rule: Double up (make a quad for bolted anchors). Multi-leg for trad anchor (3 or more anchor points) as lead climbing puts more force on the anchor.

If using trees and such make a multi-leg for TR anchor and watch out for abrasion on the edge where the anchor passes over the top of the cliff.

Standard

Well, nothing much to say. Standard product. I got what I expected! Very useful to have it. Anchors, friction knots, or even to rappel from a bolt if you dont have a quick link ready.

Stretching?

Does anyone know how much this stuff stretches? %?

Great for anchors

I use this cord for equalizing anchors and it works fine. It does it's job.
