Over the weekend we received a Product Warning Notice from Tech Rock regarding the inspection of some of their anchors. The Anchors under potential risk fall under the following conditions:
- V-shape anchors, 304 stainless steel. References : 325, 363, 393 , 404, 738, 392 and 394
- subject to intensive use.
- V anchors with rust or visible cracks
- placed on corrosive environments, including urban or high traffic areas
For these anchors suspicious to be under risk, as a preventive safety action, Tech Rock recommends the use of stainless steel, 7 mm maillons with a minimum breaking strength of 30 kN to by-pass the first link of the chains (the one connected to the hangers), as shown in the attached picture.
This solution protects the weak SCC point of the anchor. In case of breaking we recommend to replace the complete anchor.

Tech Rock is working hard to find a long term solution that will commence by the change of the material to another not prone to suffer SCC. We will announce the definitive solution in the next days.
