FERO V-Tie™ is manufactured from 4.76 mm (0.19″) diameter wire conforming to CSA Standard G30.3, and is available in hot dipped galvanized (conforming to CSA CAN3-A370 and ASTM A123 requirement of 458 g / m2 / side [1.5 oz / ft2 / side] of zinc coating), or stainless steel. The legs of the FERO V-Tie™ are mortared into place at the centerline of the brick veneer. FERO V-Tie™ comes in 10 different sizes and are available to accommodate varying airspace and veneer width combinations. To determine the optimal V-Tie length: add 1/2 the veneer width plus the air space minus 12mm = the optimal V-Tie size for your project.
