Which length should you take?

The base rule doesn't change: your rope has to be at least twice the height of the longest route you want to come back down from, with margin on top. Everything else follows from that.

• 30 to 40 m — the gym. Indoor walls are short, and 30 m covers most of them. Going 40 m leaves margin on the tallest ones, and lets you cut the ends back as they wear instead of retiring the whole rope.
• 50 m — the middle ground. A sensible first rope if you climb mostly at short crags. Worth checking route by route in the guidebook.
• 60 to 70 m — the crag. 60 m is still the reference length at most bolted crags. Some routes call for 70 m, and the guidebook always says so.
• 100 m, 200 m or around 600 m — outfitting a fleet. These formats aren't aimed at the individual climber. They're what a gym, a club or a community program buys to cut its own lengths and replace them as they wear out.

In use

1. One strand. This is a single rope: no half-rope technique, no twins.
2. A stopper knot in the end, every time. Cousin also points out that a knot can cut the rope's initial strength in half: that's normal, and the standard accounts for it.
3. Find the middle mark before every rappel and every long lower.
4. Go easy on fast lowers and constant top-roping. Cousin warns about it explicitly: they burn the rope and speed up wear. Alternate which end takes the wear, and rotate the ropes you have in service.
5. Frost and moisture. Wet or frozen, a rope gets more sensitive to abrasion and loses some of its initial strength. Let it dry in the shade, in open air.

Care and service life

A rope swells with use and can shrink by up to 5%: check the real length now and then, because a 60 m rope you bought three years ago isn't necessarily 60 m anymore. Cousin asks for a periodic inspection at least once every 12 months from the date of first use; the inspection record sheet supplied with the rope is there to log it.

Wash in clean water, dry in the shade, store dry and away from light and chemicals. For retirement criteria and service life, refer to the Cousin instructions supplied with the rope.

Can it be used as a half rope or as twins?

No. The Tepee is certified as a single rope and nothing else: one strand catches the fall. It isn't used in half-rope technique and it isn't used as twins. Those uses need a rope certified for them.

What length for the gym, and what length for the crag?

In the gym, 30 m covers most walls and 40 m gives you margin. At the crag, 60 m is the reference length, 70 m at the crags that call for it. Either way, the rope has to be at least twice the height of the route you're coming back down from.

What does the LongLife treatment actually do?

It impregnates every sheath yarn individually, to slow down dust and moisture working their way in. Cousin presents it as a longevity argument. The Tepee carries no water-absorption certification under EN 892, though: for ice or for snowy alpine terrain, pick a rope that states that certification explicitly.

Will it run in my belay device?

That's decided by your device's diameter range, not by the rope. The device manufacturer states it, on the product and in its instructions. 10.2 mm is a common diameter, but several recent devices are built around thinner ropes: check before you order.

What's the middle mark for?

Spotting the middle of the rope at a glance, above all before a rappel, or to judge from the anchor how much rope is left. Cousin applies it at the factory. It fades with use: never rely on it alone, and keep a stopper knot in the end.

Can I order a spool or bulk length to outfit a gym?

Yes. The 100 and 200 m spools and the bulk length of around 600 m fall under our B2B program. Email us at information@shopclimbing.com with your quantities: we confirm price, lead time and availability with Cousin before anything goes through.
