    Pro-Key is a stay in place metal control joint former for use in concrete flatwork as a control or construction joint. The tongue and groove design provides excellent load transfer for heavy traffic. The use of metal keyed control joint eliminates costly form stripping and saw cutting and slow checker-board placement of concrete. Pro-Key is manufactured of 24 gauge, G60 hot dipped steel. Each piece is punched on 6” centers for dowel bar knockouts.

    Advantages of PRO-KEY™

    • 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.
    • Location of the key is 1/2 depth of slab as specified by ACI & PCA.
    • LOCK SLOT™ stakes double as a butt splice.
    • Radius formed key eliminates the sharp angles that produce a spalling tendency.
    • ULTRA FINE profile at top edge eliminates surface voids, reduces spalling and produces architecturally pleasing joint lines in the finished slab.
    • Tongue and groove design provide excellent load transfer characteristics for heavy wheeled traffic and prevents uneven settling associated with aggregate interlock.
    • Eliminates costly form stripping and saw cutting. Replaces the slow and costly method of checker-board placement of concrete.
