Description


Metal keyed control joint system for concrete slabs.


Features


  • Screed Key produces a smooth, flush surface joint that requires no filling
  • 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
  • Ultra fine profile at top edge eliminates surface voids, reduces spalling and produces architecturally pleasing joint lines in the finished slab
  • Radius formed key eliminates the sharp angles that produce a spalling tendency
  • Location of the key is 1/2 depth of slab as specified by ACI and PCAs
  • Tongue and groove design provide excellent load transfer characteristics for heavy wheeled traffic and prevents uneven settling associated with aggregate interlock
  • The use of Screed Key Joint minimizes random cracking
  • 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
  • LOCK SLOT™ stakes double as a butt splice
