2.1 Strength Specifications

The Spec MBS is the catalog specification of each webbing.

The Batch MBS and the Sewn Loop MBS are those of each webbing's current production batch; a webbing produced in a separate batch for each colorway is listed once per colorway, with that colorway's batch. The batch code links to that batch's report, which lists every break test behind the figures.

The Batch MBS and the Sewn Loop MBS are the average recorded breaking force minus 3 standard deviations (3σ) of that batch's break tests, as ISA 41 sets out in section 10.5.1 for the webbing and in section 11.5.1 for the sewn loop. Axiom MK2 and Silk 99 are classed on their sewn loops: their webbing MBS was not tested independently of the loop, so only the Sewn Loop MBS is stated. A webbing with no released batch report shows its catalog values and no batch code; where a batch did not measure a figure, the catalog value is shown.

UHMWPE-based (HMPE) webbings are not suitable to be used with webbing anchors and grips. Axiom MK2 and Silk 99 are both UHMWPE-based and as such, should not be used with webbing anchors or grips.

2.2 Other Specifications

Width, thickness and weight are those measured on each webbing's current production batch where the batch recorded them, otherwise the catalog value. Material and weave structure are catalog values.

Balance Community tests its webbings following the methods of ISA 41 and publishes the results as batch reports. ISA certification of these webbings is pending. Until it is granted, the ISA class shown is derived from each webbing's current batch report (webbing MBS and sewn loop MBS) against the strength classes of ISA 41 section 3.4, and is marked as derived.

1. Webbing. Available in any length from 1 meter to 1,000+ meters.
2. Sewn Loop - End 1 - Sleeved. A protective sleeve is added to the webbing prior to sewing. This option is preferred for any end where contact with hardware is likely.
3. Sewn Loop - End 2 - Naked. No sleeve is added to the webbing prior to sewing. This option is for those that are hyper-concerned with weight and bulk within webbing-to-webbing connections.
4. Stitching. The stitching for the sewn loop(s). The pattern depends heavily on the webbing type. For more information on the sewn loop for the specific webbing you have, check our website shown under Manufacturer Contact.
5. Label. This label provides specific information about the webbing (see Sewn Loop Tag Nomenclature for more info). If the webbing has at least 1 sleeved sewn loop, it will be added to that end of the line. If both ends are naked, the label is added to one of the loops.

1. Balance Community Logo & Company Name
2. General Warnings
3. Manual and ISA icons — shown here with the generic ISA APPROVED mark; a certified webbing’s tag carries the ISA label for its own strength class (A+, A, B or C), and uncertified webbings carry none
4. Recommended maximum service lifetime for this webbing, in days exposed to the elements / days in use (ISA 41 Annex C)
5. Webbing Model Name
6. MBS and Sewn Loop MBS
7. Piece Length (hand written)
8. Batch Number (hand written)
9. Date of manufacture in YYYY.MM.DD format (hand written)
10. Piece ID, left blank for the user to fill in. Used to identify specific piece of webbing, if many are owned from same batch

Elongation at 5 kN and 10 kN is measured with the ISA 41 elongation method (section 9: 1 kN pretension, 200 mm gauge length) on a production batch of the webbing, and applies to every colorway of it.

The full stretch curve of each webbing, measured using our preferred stretch testing method, is on that webbing's product page: follow the webbing's name in the table above. The method is described in our "Webbing Stretch Testing Methods" article in Slack Science.

New webbings were used in each of these stretch tests. Please note that humidity, moisture, age, usage, and exposure to the elements can change the stretch behavior of slackline webbings. The data above is to be used for informational purposes only and should not be taken as fact for how your webbing will stretch at any moment in time. We provide this data to give our customers a means to compare the stretch of all our webbings.

Limited Warranty: for one year following purchase to the original buyer. We warrant that our products are free from defects in material and workmanship. Excluded from this warranty are normal wear and tear, modifications and changes, as well as damage caused by misuse.

A full recall is only applicable to new and unused products.

The three intended ways to terminate one end of the webbing are shown in Fig. I under Webbing Anchoring.

Slackline webbing is meant for walking on and should only be used with energy absorbing systems (such as dynamic anchoring materials, energy absorbers, etc...) and slack must be kept out of the system to prevent high impact falls. It is intended for use by medically fit, specifically trained and experienced users. The device is only suited for attaching oneself to a highline with a tether.

The user is responsible for the surveillance of the operating and working load.

Avoid contact with heat, abrasive and sharp objects, corrosive substances or solvents. Wash the webbing after contact with salt water or sand. Wash with clean water and if necessary, add a small amount of neutral soap to remove persistent dirt or sand. If the Slackline Webbing is damp or wet, leave it out to dry in shade or away from direct heat sources.

Moisture, ice, salt, sand, mold, snow, chemicals and other factors can prevent proper operation or can greatly accelerate wear.

Check all parts for deformation, corrosion, wear, etc. Verify that the individual fibers along the length of the Slackline Webbing are free from breaks, abrasions, and lacerations that could potentially reduce the strength and lifespan. Regularly inspect and monitor your system, confirming proper connections, equipment position, fully locked connectors, etc.

Repairs or Modifications to any part of the Slackline Webbing are not permitted and only allowed by the manufacturer or those authorized in writing by the manufacturer.

The lifespan of the Slackline Webbing greatly depends on the usage. In extreme cases, the Slackline Webbing can be retired after the first use. Monitor your device and pay close attention to how much use it has gotten.

Retire the Slackline Webbing from service and destroy it if it is significantly loaded beyond the WLL in any configuration, does not pass inspection or there is any doubt about its safety, is misused, altered, damaged, or exposed to harmful chemical. Consult the manufacturer if you have any doubts or concerns.

To transport and/or store your slackline webbing, put it in a secure bag either flaked or coiled nicely. Avoid packing hardware or sharp objects in the same bag as the webbing to prevent any accidental damage.

To anchor the Slackline Webbing, you must use a standard webbing locker, as defined by ISA:51 (weblock), or the provided sewn loops. If using the sewn loop, anchor it to the pin side of a shackle, as shown in Figure I above on the right side. Do not attach the sewn loop to a carabiner, or any other type of connector outside of ISA Approved Connectors.

If you plan to use a standard webbing locker, follow the loading instructions for that specific webbing locker. Be sure to tie off the webbing after tensioning is complete, as defined in the webbing locker instruction manual.

11.1 Webbing grabbing devices

Webbing grabbing devices (grips) hold the webbing by friction. A grip that is not suited to the webbing can slip or damage the webbing. Only use a grip that its manufacturer approves for the width and material of your webbing, and follow that grip's instructions and load limits. Do not use grips on UHMWPE-based webbings. The grips listed as compatible with each webbing are on that webbing's product page.

The lifespan of your slackline webbing depends on a few key things:

1. The ISA Class of the webbing
2. How often it is used
3. How hard it is used

Below is the ISA Recommended Maximum Service Lifetime (RMSL) chart to help determine the lifespan of your slackline webbing, assuming normal use.

† Balance Community recommendation, not an ISA 41 Annex C figure.

Log each usage of your slackline webbing to have a better idea for when to retire the piece, according to the chart in Webbing Usage Lifespan.
