The Singing Rock Eye Sling W2004 x 120 is a two-layer sewed sling with eye and wear indicator. This is produced from two items, one inserted into the second one. In case of outer webbing damage the user is immediately advised on danger and hazard connected with further use by seeing the red color of the inner strap. EYE SLING has to be used as a component of a fall arrest system The sling is tested according to EN 354 standard for lanyards and according to EN 795B standard for anchor devices If the outer webbing is damaged, eye sling can still hold 22 kN (but SINGING ROCK recommends putting the damaged eye sling out of use at once!)
