Canopy Series
Canopy-24
A 24-strand climbing line that runs true through any friction hitch.
PolyesterDouble Braid
- Max MBS
- 9,800 lb
- Diameters
- 7/16" – 9/16"
Ascent Series
Ascent NFPA-G
NFPA 1983 General Use. Built to be trusted, not admired.
KernmantlePolyesterNylon
Schematic — Parallel or twisted core in a tight sheath
Low-stretch kernmantle, polyester sheath over a nylon core, built and tested to NFPA 1983 General Use. The sheath balances descender grip against concrete-edge survival.
When to specify this
Life-safety rope is not a place for optimisation. Ascent is specified to a standard, tested to it, and documented for the AHJ.
Engineering notes
- Meets NFPA 1983 General Use requirements
- Static elongation under 2% at 10% MBS. Controlled descent, minimal bounce
- High sheath-yarn count for edge-abrasion resistance
- Batch certificate and date-of-manufacture marking on every length

Typical applications
Specifications
Minimum break strength is the value we publish and test to — not an average, and not a working load. Divide by your design factor before putting a number on a drawing.
| Diameter | Min. break strength (lb) | Weight (lb/100 ft) |
|---|---|---|
| 7/16" | 8,992 | 6.8 |
| 1/2" | 10,800 | 8.6 |
| 9/16" | 12,600 | 10.4 |
Working load shown at a 5:1 design factor for illustration only. Use the load calculator to apply the design factor, sling angle and termination efficiency your application actually requires.
Weights are nominal and vary ±5% with finish and coating. Elongation measured on new rope after bedding-in; expect higher values on the first cycle. Splice efficiency assumes a correctly made splice with the specified bury length.
Load against elongation
Measured to 30% of MBS. Beyond that the curve is extrapolated from the fibre, and drawn dashed to say so.
Load vs. elongation
Ascent NFPA-G — stretch under load
Elongation as a percentage of original length, plotted against load as a percentage of minimum break strength. Drag, or focus the plot and use the arrow keys, to read any point off the curve.

- Measured
- Solid — measured at 10, 20 and 30% of minimum break strength, interpolated with a monotone cubic so the fit cannot overshoot.
- Dashed — extrapolated to 12% using published Polyester elongation at break. Inferred, not measured. Do not design to it.
- Shaded — working load at a 5:1 design factor, i.e. up to 20% of MBS.
| Load (% of MBS) | Elongation (%) | Source |
|---|---|---|
| 0 | 0 | Origin |
| 10 | 1.8 | Measured |
| 20 | 3.4 | Measured |
| 30 | 5.1 | Measured |
| 100 (break) | 12 | Extrapolated from Polyester elongation at break |
Strength to weight
Break strength per pound of rope, across the catalogue. This is the number that decides what a two-person crew can rig.
Strength-to-weight
12 ropes, ranked highest first
STRENGTH-TO-WEIGHT — LB PER LB/100 FT
Break strength divided by weight per 100 ft, best size in each range. Numerically this is breaking length in hundreds of feet — the length of rope whose own weight equals its break strength.

| 1 | Apex-12 | 6,615 |
| 2 | Apex-12 MAX | 6,290 |
