The Evolution of Petzl Serial Numbers – A complete guide

Did you know that every Petzl product now has a unique serial number, and the numbers and digits have a meaning?

In the early days Petzl’s serial numbers were 4 digits separated by a space e.g. 04 06, this simply told the user the month (April) and then the year (2006) of manufacture. This design was followed by a 6 digit format like the one below (01009A) which gave a little more information to the user, 01 is the year of manufacture (2001)/ 009 is the day of manufacture in that year (9th January) / A is the code of the person who inspected the product.

Next came an 11 digit format Petzl serial number:

13 Digit Petzl Serial Number
This example shows the serial number (15041OI4974) with the first two numbers (15) corresponds to the year of manufacture I.e. 2015, the next three numbers (041) corresponds to the day of manufacture in that year I.e. the forty first day of 2015 (10 February), the two letters (OI) is the code of the person who inspected the product and the final four numbers (4974) is the individual product number / incrementation.

You may find products with the same first five numbers (i.e. have been manufactured on the same date), which have been inspected by the same person (so the first 7 digits will be the same) BUT the complete last four numbers will be different (0001, 0002 etc) and it is this difference that makes the full serial number unique.

Gradually being implemented (from 2016 onwards), the serial numbers will take the form of a 13 digit design and will look like the following:

The first two numbers (16) are the year of manufacture (2016), the single letter (C) is the month of manufacture (March), the next sevens numbers are the batch number, and the final three numbers are the incrementation.

And if you are wondering where the serial numbers are hidden on the Petzl Croll and Petzl Basic, check behind the catch!

Where is the serial number on a Petzl Croll and a Petzl Basic

On the Avao harness range the serial number is on a white tab tucked away in a small pocket in the waist belt padding on the right hip. For the new Petzl Newton and Volt harnesses, look for the pocket sewn into the top of the back section of the left leg loop.


Petzl Volt Wind Harness for wind turbine technicians

The Petzl Volt Wind Harness, which offers both fall arrest and work positioning capabilities for wind turbine technicians, is now in stock at and at our Holmfirth store.


With wind power having become a key part of the UK’s electricity generation infrastructure, there is a growing demand for specialist PPE for those working at height to inspect and maintain the country’s 5,200 onshore and 1,400 offshore turbines.

The new Volt Wind Harness is Petzl’s response to that demand and boasts a number of cleverly designed features to cope with some of the challenges posed by working on turbines.

One of the main advantages it offers over standard harnesses is rear wear protectors to stop the webbing being damaged by rubbing against the inside of the wind turbine body when moving about in the tower. This simple addition increases the durability of the Volt Wind Harness, giving it a longer safe life expectancy.

The Volt Wind Harness features a selection of attachment points to ensure it is compatible with the relevant safety and positioning equipment while you work on wind turbines. They include sternal and dorsal attachment points for fall arrest systems, side attachment points for positioning lanyards and a rear waistbelt point for a restraint lanyard.

Perhaps most usefully of all if you use vertical rail or cable-based fall protection systems, the ladder climb attachment is on the waist and distributes the load on the waistbelt for increased comfort during progression. In the event of a fall, the attachment point automatically moves upwards to leave you suspended in an upright position rather than being pivoted at the waist.


Further safety features include foldaway side D-rings to prevent snagging when not in use and a stowage system on each shoulder strap to keep fall arrest lanyard connectors out of the way when they are not being used. The stowage points are designed to release in the event of a fall to allow the fall arrest lanyard to fully deploy.

While safety is the primary focus of all good PPE, it also helps if it is comfortable – particularly if you are going to be suspended up a wind turbine for any period of time. Fortunately, the Petzl Volt Wind Harness was designed with that in mind, making it an ideal choice for longer duration maintenance and repair tasks – particularly if you add the optional Volt Harness Seat.


The combination of lightweight, breathable mesh jacket and quick release buckles on the waistbelt and leg loops make the harness easy to put on and ensure it keeps its shape. Once you are wearing the harness, you will benefit from a design that gives optimal freedom of movement, a semi-rigid waistbelt for maximum support and adjustable leg loop foam. There are even loops that allow a toolbag to be clipped to the harness for easy access.
