The Slotted Block Tie (Type II) was developed for masonry cavity wall construction where significant differential movement between the veneer and the backup block wythe is expected, such as high walls or multi-storey buildings with full height veneer. The Slotted Block Tie (Type II) allows for up to 60 mm (2.4") of construction adjustability and up to 25 mm (1") differential movement between the veneer and the backup wythe.

Note that as the Slotted Block Tie (Type II) is only capable of transferring forces perpendicular to the wall and not parallel to the wall, composite action cannot be achieved between the masonry wythes. For the design of ShearTruss masonry cavity wall systems (i.e. composite masonry cavity walls), see Fero Block Shear™ Connector.
