The Pac-Tie System is ideally suited for wood frame construction where insulation is often not included in the cavity (and tie surface-mounting is thereby facilitated), where frame shortening of the structure due to shrinkage must be accommodated, and for most Building Code jurisdictions, where masonry veneer can be supported from the foundation of the structure to heights of about 11 m (36 ft.).

AB-Clip: The AB-Clip (Figure 2) is manufactured from 16 gauge sheet steel [(1.367 mm (0.0538”) minimum base steel thickness] and is available in both hot-dip galvanized finish and stainless steel. The weight of the hot-dip galvanized finish in not less than 460 g/m2/side (1.5 oz/ft2/side), and satisfies the requirements of CSA A370 (which references ASTM A123), ACI 530.1/ASCE 6/TMS 602 (which references ASTM A153, Class B), and the International Codes (which reference ASTM A153, Class B). The AB-Clip is offered in one standard size and configuration, as detailed in Figure 2.

V-Tie™: The V-Tie™ (Figure 3) is manufactured from 4.76 mm (0.19”) diameter wire and is available in both hot-dip galvanized finish and stainless steel. The weight of the hot-dip galvanized finish is not less than 460 g/m2 (1.5 oz/ft2), and satisfies the requirements of CSA A370 (which references ASTM A123), ACI 530.1/ASCE 6/TMS 602 (which references ASTM A153, Class B), and the International Codes (which reference ASTM A153, Class B).

The V - Tie™ is available in a variety of standard lengths to accommodate different thicknesses of masonry veneer and design widths of air space. The design length of V-Tie™ should be selected so its legs are positioned along the centreline of the masonry veneer. Varying lengths of V-Tie™ can be appropriately selected by the mason on the jobsite to facilitate in-situ adjustment normal to the structural backing (where needed to accommodate construction tolerances). Standard lengths of V-Tie™ include 60 (2.4”), 80 (3.1”), 100 (3.9”), 120 (4.7”), 140 (5.5”), 160 (6.3”), 180 (7.1”), 200 (7.9”), 225 (8.9”) and 250 mm (9.8”) lengths. By selecting the appropriate length of wire V-Tie™, cavity widths of 15 mm (0.59”) to 200 mm (8”) can be accommodated. Specify the V-Tie™ size as the distance from the exterior face of the structural sheathing to the centreline of the masonry veneer.

Backer Plate: The Backer Plate (Figure 4) is manufactured from 16 gauge sheet steel [(1.367 mm (0.0538”) minimum base steel thickness] and is available in both hot-dip galvanized finish and stainless steel. The weight of the hot-dip galvanized finish in not less than 460 g/m2/side (1.5 oz/ft2/side), and satisfies the requirements of CSA A370 (which references ASTM A123), ACI 530.1/ASCE 6/TMS 602 (which references ASTM A153, Class B), and the International Codes (which reference ASTM A153, Class B). The Backer Plate is offered in one standard size and configuration, as detailed in Figure 4.
