Duraline 10.5 mm

The Petzl DURALINE 10.5 mm is a high-strength, low-stretch kernmantle rope built for work at height, rope access, and rescue. Its sheath is made entirely from aramid fibre, giving it markedly better resistance to abrasion, sharp edges, and heat than a classic sheath.

Rope access technicians and rescue teams choose the DURALINE 10.5 mm where a rope must survive repeated lowering, sharp edges, and incidental heat: Petzl rates it twice as abrasion-resistant, and two to three times more cut-resistant, than its AXIS 11 mm rope. Petzl's Canadian site lists it as the DURALINE 10.5 mm CUSTOM, made to order in one-metre increments; Siren Safety's three references match the fixed factory lengths Petzl documents for the equivalent DURALINE 10.5 mm US SIZE product — confirm the exact cut length before ordering.

Common questions

What NFPA rating does the Petzl DURALINE 10.5 mm carry?

The Petzl DURALINE 10.5 mm is certified to NFPA 2500 Technical Use, not NFPA 2500 General Use, so confirm which use class your application requires.

What length does each Siren Safety reference correspond to?

Siren Safety's three references match Petzl's documented lengths for the equivalent US-size product, approximately 45.7 m, 61.0 m, and 182.9 m; confirm the exact cut length before ordering, since the Canadian page itself sells this rope made-to-order.

What makes the DURALINE sheath different from a standard rope?

The Petzl DURALINE 10.5 mm uses a sheath made entirely from aramid fibre, twice as abrasion-resistant and two to three times more cut-resistant than its AXIS 11 mm rope's standard sheath.
