A load transfer plate pocket configured to receive a load transfer plate for transferring loads across a joint between a first cast-in-place concrete slab and a second cast-in-place concrete slab, the load transfer plate pocket comprising: an attachment wall defining a load transfer plate receiving slot; and a generally triangular shaped body extending from the attachment wall, the body including: (a) a generally triangular upper wall; (b) a generally triangular lower wall, said lower wall spaced apart from the upper wall such that the load transfer plate can freely move between the lower wall and the upper wall; (c) a first side wall connected to the upper wall and to the lower wall; (d) a second side wall connected to the upper wall and to the lower wall; (e) a first load transfer plate positioner extending from the first side wall; (f) a second load transfer plate positioner extending from the second side wall; characterised in that the load transfer plate pocket further comprises: (g) a centering third load transfer plate positioner extending from the first side wall and configured to engage a first tip of the load transfer plate that partially defines a widest area of the load transfer plate; and (h) a centering fourth load transfer plate positioner extending from the second side wall and configured to engage a second tip of the load transfer plate that partially defines the widest area of the load transfer plate, and in that the load transfer plate pocket is configured and sized such that the load transfer plate can be positioned in the load transfer plate pocket beyond a center line of the load transfer plate. an attachment wall defining a load transfer plate receiving slot; and a generally triangular shaped body extending from the attachment wall, the body including: (a) a generally triangular upper wall; (b) a generally triangular lower wall, said lower wall spaced apart from the upper wall such that the load transfer plate can freely move between the lower wall and the upper wall; (c) a first side wall connected to the upper wall and to the lower wall; (d) a second side wall connected to the upper wall and to the lower wall; (e) a first load transfer plate positioner extending from the first side wall; (f) a second load transfer plate positioner extending from the second side wall; characterised in that the load transfer plate pocket further comprises: (g) a centering third load transfer plate positioner extending from the first side wall and configured to engage a first tip of the load transfer plate that partially defines a widest area of the load transfer plate; and (h) a centering fourth load transfer plate positioner extending from the second side wall and configured to engage a second tip of the load transfer plate that partially defines the widest area of the load transfer plate, (a) a generally triangular upper wall; (b) a generally triangular lower wall, said lower wall spaced apart from the upper wall such that the load transfer plate can freely move between the lower wall and the upper wall; (c) a first side wall connected to the upper wall and to the lower wall; (d) a second side wall connected to the upper wall and to the lower wall; (e) a first load transfer plate positioner extending from the first side wall; (f) a second load transfer plate positioner extending from the second side wall; characterised in that the load transfer plate pocket further comprises: (g) a centering third load transfer plate positioner extending from the first side wall and configured to engage a first tip of the load transfer plate that partially defines a widest area of the load transfer plate; and (h) a centering fourth load transfer plate positioner extending from the second side wall and configured to engage a second tip of the load transfer plate that partially defines the widest area of the load transfer plate, and in that the load transfer plate pocket is configured and sized such that the load transfer plate can be positioned in the load transfer plate pocket beyond a center line of the load transfer plate.
