Petzl Professional Rope Clamps

In this category you will find rope clamps for various applications such as ascending the rope (single and double strand), use as a return stop in a pulley system or for setting up pulley systems. Different types of rope clamps are used for this purpose: Hand ascenders, chest ascenders in combination with a hand ascender, foot ascenders and auxiliary rope clamps. The accessories required or optional for the rope clamps can also be found in this category.

Type of rope clampDescriptionArticle
Hand ascender Suitable for ascending the rope with two rope clamps.
The rope clamp forms the "safety backup" and is thus part of the safety chain. The advantages of the hand ascender are easy handling and facilitation of the ascent.
Chest ascenderSuitable for rope ascents when used with a hand ascender. The chest ascender is part of the belay chain and facilitates the ascent.CROLL
Foot ascenderThe foot ascender is used exclusively as a climbing aid and should always be used in conjunction with a hand ascender or chest ascender. The advantages of the foot ascender are support when using special climbing techniques (e.g. climbing stairs) and relief during long ascents (prevents rapid fatigue).PANTIN
Auxiliary rope clampThe auxiliary rope clamp is a rope clamp in minimal form. It can be used to reach belays that are longer than the actual rope. Furthermore, a makeshift rope clamp can be used to secure the exit from a route or also to set up a pulley system.TIBLOC

CE conformity mark

By affixing this mark, the manufacturer confirms on his own responsibility that a product complies with all the relevant regulations of the European Union. It is to be understood like the technical passport of the product and is considered as a basic requirement for a sale within the European Economic Area. The CE conformity mark thus indicates that a product complies with the required directives and is officially certified. The number after the CE conformity mark indicates the certification body.

EN 567

Rope clamp
Mechanical device which, when applied to a mountain rope or cord of appropriate diameter, clamps in one direction when loaded and can be moved in the opposite direction.

Rope clamps must be constructed in such a way that the rope or cord can only be released from the rope clamp by at least two independent actions when the rope clamp is used according to the manufacturer's instructions. All edges must be free of burrs or sharp edges.

    The following markings are mandatory for the manufacturer to affix to the product:
  • Name of the manufacturer
  • Minimum/maximum diameter of the rope/rope cord in mm
  • Ø-sign in front of the mm indication
  • Symbol indicating the direction of use
  • CE marking with 4-digit identification number
  • Reference to instructions for use.

EN 12841 type B

This European Standard applies to rope setting devices intended for use in rope access systems. This standard specifies requirements, test methods, marking and manufacturer's information. Rope access devices complying with this European Standard may be designed for use by one person or, in the case of rescue, for simultaneous use by two persons.

    EN 12841 type B tests the rope adjusting device and is defined by the following characteristics:
  • Manually operated rope setting device which, when attached to a working rope, locks under load in one direction and slides freely in the opposite direction. Type B rope adjustment devices shall withstand a force of 4 kN for 3 min on a suspension device with a stop knot.
  • The minimum service load is determined by means of the slip, which must be less than 100 mm for type B.
    The following markings are mandatory for the manufacturer to affix to the product:
  • Manufacturer
  • EN 12841
  • Model designation
  • Batch number
  • Year of manufacture
  • Smallest and largest diameter of the rope in mm
  • Reference to instruction manual
  • Type of rope setting device (A, B, C, A/B, A/C, B/C)
  • Diameter of guide
  • Max. Nominal load
  • Type of guides to be used
    - EN 1891, form A
    - Other types or other constructions
  • Indication of correct alignment in normal use
  • CE marking with 4-digit identification number


NFPA stands for National Fire Protection Association and is a US standard for fire protection. NFPA publishes a comprehensive set of fire protection regulations (National Fire Codes) that are mainly used in the USA.


With the EAC marking, the manufacturer, distributor or authorized representative declares that the product, which is placed on the market for the first time in the territory of the Eurasian Economic Union, complies with the applicable safety requirements specified in the Technical Regulations of the Eurasian Economic Union. If the conformity test is successful, then the products must be marked with the EAC conformity mark. EAC is an abbreviation for Eurasian Conformity. It is similar in content to the European CE mark.
