The Pac-Tie (Plate Adjustable Connector Tie) system is designed to facilitate the placement of an adjustable tie on top of protected drywall or structural sheathing. Protected drywall is defined as per CSA Standard CAN3-A370-04 "Connectors for Masonry", ACI/ASCE/TMS/518 and U.B.C. Structural sheathing is described in the National Building Code of Canada. The Pac-Tie system is illustrated in Figure 1.

The Pac-Tie system provides resistance to damage of the protected drywall or structural sheathing from the concentrated compressive loads, vibration, and other movements produced by the masonry veneer.

The Pac-Tie system provides for construction adjustability, allows for differential vertical movement between the backup wall and the veneer, and can accommodate cavity widths of 15 mm (0.59") up to 200 mm (8").

The Pac-Tie system is ideally suited for wood frame construction, as it can accommodate the frame shortening shrinkage of the wood structure, and for buildings where the maximum unsupported masonry veneer height approaches the allowable height of 11 meters (36') (CSA CAN3-S304-04).
