Owners, architects and masons can be confident in the performance of an "X-SEALED" metal stud / veneer wall. The X-SEAL™ Anchor is the next generation veneer anchor from H&B. The original DW-10-X® Anchor was developed to address the problem of possible long-term deterioration of the insulation or wallboard. The pronged legs bridge the sheathing and abut the steel stud, affording independent, positive anchorage. Compression of the sheathing by positive loads is also prevented. The X-SEAL Anchor improves upon the DW-10-X by moving the horizontal pronged legs in from each end, enabling the backplate portion of the anchor to effectively seal the wallboard /insulation. This helps to maintain the integrity of the vapor barrier and prevents the ingress of air and moisture through the sheathing. The pronged legs are now also rib-stiffened and oriented closer to each other than on the original DW-10-X, thus enhancing the compressive strength BY OVER 20%!
