| CAT-TIE PERFORMANCE AND PLACEMENT
The Cat-Tie can be utilized with masonry walls constructed of solid or hollow units. For solid masonry walls, the legs of the V-Tie™ must be placed at the centerline of the wall in full mortar bed joints. For hollow masonry walls, the legs of the V-Tie™ must be placed at the centerline of the exterior face shell of the masonry unit. For increased pull-out capacity, the legs of the V-Tie™ can be grouted into the cores of the hollow masonry units.
The unique configuration of the V-Tie™ provides for much greater pull-out (or push-out) capacity from the mortar joint of the brick veneer than similar ties currently on the market. The area of mortar effective in providing support to the V-Tie™ is illustrated in Figure 4. The effective mortar area for a number of typical ties is also shown in the Figure. A comparison of the pull-out capacities of the various tie types is presented in Table 1.
