The 3.5mm SOP Interlocking plate is available from 3 to 20 holes in length. A 30 hole plate is available for special order. The 3.5mm system requires the use of bending tees during bending and twisting (Product code 800400135). The hole spacing is 12mm from centre to centre of the screw holes and allows close positioning of 2 plates alongside each other and therefore position 3 screws in a 12mm fragment if necessary. Dedicated bending irons, drill guide and bending tees are necessary and are listed separately.
