VIR / VIRH Internal Head Restraint

The VIR / VIRH Internal Head Restraint is a high-performance solution designed to control lateral movement at wall heads by securely restraining them to structural soffits. Engineered for flexibility, it allows for vertical movement—ideal for accommodating structural factors such as beam deflection. Available in two versions, the standard VIR and the VIRH (holed) for use with Tek Screws or bolts, as well as options with head channels, this restraint offers versatile installation across a wide range of construction scenarios. Manufactured from grade 304 stainless steel, it ensures long-term durability and corrosion resistance in demanding environments.
