PETZL's engineering ensures consistent quality throughout the ROCPEC accessory lineup.

Applications

Key benefits

• Ultra-light at 37 g: no perceptible extra load on the harness or route-setting rack during extended work at height
• Steel construction: durable under repeated rotational stress against abrasive or wet rock surfaces
• Dedicated 8 mm PETZL ROCPEC P26 interface: full system compatibility with no intermediate adapters needed
• 15 N.m tightening torque: reliable setting of 12 mm self-drilling anchors without over-stressing the rock substrate
• Made in France: manufactured at the PETZL facility in Crolles (38920), ISO 9001-certified production
• 3-year manufacturer warranty: manufacturer quality commitment across the entire ROCPEC accessory range

Usage precautions

• Rock quality: avoid very friable, weathered limestone or clay-bearing rock — risk of insufficient anchor hold
• Maximum torque: do not exceed 15 N.m to protect both the rock face and the adapter thread
• Minimum depth: strictly observe the 80 mm minimum specified in the official technical notice
• Dedicated use: use exclusively with the ROCPEC P26 hand drill — not compatible with other striking tools
