48 and brace 44 defines a second adjustment slot 50 brace 42 and brace 44 are coplanar face 46 is similar to face 24 and includes flanges 52 similar to flanges 28 another alternative apparatus 16 u2033 is shown in fig5 apparatus 16 u2033 generally includes a brace 54 and a face 56 brace 54 can define at least one adjustment slot 58 a plurality of flanges 60 extend outwardly from face 56 each successive pair of flanges 60 limits movement of one bar such as post tensioning bar 18 or rebar 20 other flange configurations also are possible for example instead of having two flanges for each bar there could be a total of n 1 flanges for every n bars thus three flanges could be used to receive two bars with the first bar housed between the first and second flanges and the second bar housed between the second and third flanges yet another alternative apparatus 16 u2032 u2033 is shown in fig6 apparatus 16 u2032 u2033 generally includes a brace 70 and a face 72 brace 70 can include at least one adjustment slot 74 a plurality of flanges 76 a d extend outwardly from face 72 in a direction generally perpendicular to the previously described embodiments thus flanges 76 a d extend in a plane perpendicular rather than parallel to the longitudinal axis of the bar flanges 76 a d define a bar receiving area 78 flanges 76 a and 76 b are generally coplanar flanges 76 c and 76 d also are generally coplanar as shown in fig6 flanges 76 a and 76 c are on a first side.
