Armbury Static InterCore 10.5mm and 11mm

The ARMBURY STATIC INTERCORE semi-static rope combines low elongation with technology designed to strengthen the connection between sheath and core. By reducing sheath slippage, INTERCORE helps support consistent performance and a longer service life. Choose 10.5 mm or 11 mm to match your compatible rope equipment and system requirements.

A stronger sheath–core connection

For professionals who rely on their rope throughout the working day, construction matters as much as strength. INTERCORE technology improves the connection between the outer sheath and inner core to reduce relative movement, with 0% sheath slippage reported on both technical sheets. Polyamide construction and clearly specified performance figures make it easier to select the right diameter for your system.

Key features

• INTERCORE technology: Improves sheath–core connection to reduce sheath slippage and support rope lifespan and performance.
• Semi-static construction: Reported elongation of 3.2% for 10.5 mm and 3.4% for 11 mm.
• 0% reported sheath slippage: Listed for both diameters in the manufacturer's technical data.
• Polyamide material: PA construction with a 55% core and 45% sheath mass distribution.
• Two diameter options: Choose according to equipment compatibility and the intended application.

Certification & Safety

This rope is certified by CE, EN 1891 and UIAA for both diameters. Read and follow all manufacturer instructions before use. Confirm compatibility with ascenders, descenders and other system components, and inspect the rope as instructed. Strength ratings are not working-load limits, and the reported fall count is a test figure, not permission to continue using a rope after a fall. Misuse can result in serious injury or death.
