Safety update for HQ4 ONE Bars

Safety First – Safety update for the latest generation of HQ4 ONE bars

Safety First applies to all HQ4 products – always and without compromise. For this reason, Invento tests the function and safety of HQ4 products in regular and repeated stress tests.

In use under tough real conditions, the knot at the end of the depower line of an HQ4 ONE Bar 2.0 has worked its way through the depower hand strap. Since a recurrence can never be excluded with absolute certainty, we need to avoid that the knot opens under extreme load and the depower line rushes through the clamcleat.

For this reason, it is MANDATORY to execute a corresponding SAFETY UPDATE for the latest generation of HQ4 ONE Bars and only use the bars again after the safety update has been carried out.

Which articles are affected?

================================================== =======================

The safety update applies to the following articles:

Art. 12055588 – HQ4 ONE Bar 2.0 – 49 cm

Art. 12055589 – HQ4 ONE bar 2.0 – 55 cm

All bars with sales from June 2020 are affected.

How does the safety update work?

================================================== =======================

A stopper ball is placed between the knot at the end of the depower line and the depower hand strap. This safety update is very easy to carry out: Open the knot at the end of the depower line – slide the stopper ball onto the depower line – close the knot at the end of the depower line again and tighten it with a flat-nose pliers (IMPORTANT: The self-adhesive nylon fabric at the end of the depower line must be outside the knot to avoid any risk of line slipping inside the knot) – done.
