On the other hand, if the anchors are far apart and the loops are tightly spread between them Anchor equalization is the process of combining two or more anchors in the build of a single equalized anchor. The choice between equalized and focused anchors depends on factors such as anchor strength, load direction, and the need for redundancy. A few examples include: SERENE: Solid (or strong), Equalized, Redundant, Efficient, No, Extension ERNEST(A): Equalized, Redundant, No, Extension, Solid (or strong), Timely, (Angles) STRADS: Solid, Timely, Redundant, Angles, Distribution, Shockload They are all basically variations […] Nov 6, 2018 · In the summer of 2015, DAV Safety Research was sent a torn chain link from an equalized anchor of FIXE.

Sep 10, 2021 · The Two Point Pre-Equalized Anchor If you’ve ever taken an anchor building class, then you’ve probably seen this one. On the other hand, self-equalizing anchors like quads or sliding x’s will adapt as the direction of pull changes over time. - The equalizing figure-8 is not redundant. But, dynamically equalized anchors really don't dynamically equalize in anything more than a 2-point anchor and, even then, equalize poorly due to clutch effect. Setting up a pre-equalized anchor requires careful consideration of anchor points, equalization, and the use of appropriate knots to ensure a reliable connection.
