  • LOCK SLOT™ stakes double as a butt splice
  • Tongue and groove design provide excellent load transfer characteristics for heavy wheeled traffic and prevents uneven settling associated with aggregate interlock

  • Ultra fine profile at top edge eliminates surface voids, reduces spalling and produces architecturally pleasing joint lines in the finished slab
  • Eliminates costly form stripping and saw cutting. Replaces the slow and costly method of checker-board placement of concrete
  • Positive stake-to-key lock of PRO-KEY™ [Patent No. 5380122] prevents costly delays associated with resetting key joint when floating concrete. Stakes interlock with slots to prevent the key from rising off the stakes
