CASES OF SLIPPAGE WITH ZIGZAG / ZIGZAG PLUS / ZILLON


We have received reports of users experiencing rope slippage while using the ZIGZAG, ZIGZAG PLUS and ZILLON. Following these reports, we have identified two defects causing the slippage. We therefore ask you to do a manual inspection and a function test of your product, to detect any possible slippage. In case your product slips, we are providing details on our after-sales returns service.

This information concerns only the following products: ZIGZAG (D022AA00), ZIGZAG PLUS (D022BA00), ZILLON (L22A 025, L22A 040, L22A 055) with serial numbers between 18L 0000000 000 and 21G 0000000 000.

Customer returns alerted us to slippage with new or slightly used ZIGZAG / ZIGZAG PLUS / ZILLON products. Following our technical investigations, we were able to identify the causes of the slippage. They are related to a variance in our production process, resulting in two types of defects in the release levers on ZIGZAG, ZIGZAG PLUS and ZILLON:

  • random malfunction of the spring effect of the upper release lever
  • variance in the surface treatment resulting in a modification of the geometry of the release lever.

This production variance causes premature wear of the release levers, resulting in slippage that can be observed after a few months of use, or even on new products.

This situation leads us to three actions: 

  1. Stop sales of current products. We are working to solve the problem with the goal of being able to deliver new products after November 1st, 2021.
  2. A request for inspection of your product by following two specific points of the PPE inspection procedure.
  3. An after-sales service offer to redress the inconvenience caused by slippage of your product (exchange or refund).

Inspection points to carry out on your ZIGZAG / ZIGZAG PLUS / ZILLON product

1. Inspecting the release levers

Check the effectiveness of the upper release lever return spring
Check the mobility of the lower release lever

Check the effectiveness of the upper release lever return spring (1) and the mobility of the lower release lever (2) for ZIGZAG, ZIGZAG PLUS. Repeat the test at least ten times.

The levers should move freely without friction.

If the results of these tests are not satisfactory, immediately stop using your product and return your product by contacting your local after-sales service center with on the contact form. If the release levers work, proceed to the next inspection point


2. Function test

ZILLON: Hang on the lanyard in single mode at a very low height: there should be no slippage. When used in double mode, verify that pressure on the release lever allows smooth and controlled sliding of the rope.

ZIGZAG / ZIGZAG PLUS: perform a function test with your rope (compatible rope diameters: 11.5 to 13 mm). Install the ZIGZAG in double mode. Suspend yourself at a very low height.

When hanging from the ZIGZAG in double mode, there should be no slippage. Verify that pressure on the release lever allows smooth and controlled sliding of the rope.

If the results of these tests are not satisfactory, immediately stop using your product and return your product by contacting your local after-sales service center
