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