The heads of this type of strap are integrated with a special anchor that can be pressed into a drilled hole. After being pressed, the arms of the anchor spread out on the other side of the hole, locking the strap in place. The pressure wings remain on the head side, providing a secure and stable fastening in the hole. The RT and FBS versions of the straps are detachable and suitable for multiple uses. Additionally, the FBS strap is made in the form of a ladder, providing greater flexibility. They are used for tying and securing cable bundles, pipes, and hoses in the automotive, aviation, household appliances, and switchgear industries.
