QuicKey™ is a stay in place metal keyed control joint former for use in concrete flatwork as a control or construction joint. When indicated on drawings or called for in specifications, the contractor shall furnish and install QuicKey™ joint system as manufactured by BoMetals, inc., Carrollton, Georgia.

Material:
QuicKey™ is manufactured of 24 gauge, hot-dipped, galvanized steel. It is furnished in 10’ lengths for 4”, 5”, 6” and 8” and 10”-12” slabs. Each piece is punched on 6” centers with dowel rod knockouts and each piece has ribs formed into it for rigidity. Special manufacturing techniques produce a continuous edge that assures the key joint has a positive lock with the tab on the stake. LOCKING-TAB™ stakes are manufactured from 13 gauge HRPO steel and are available in 12”, 15”, 18”, 24” and 30”. The removable cap measures 13/32” x 1/2”. The non-removable cap measures 5/8” x 5/8”. Both are manufactured of PVC compounds.

Advantages:

• QuicKey™ is the only galvanized joint system that features knockouts for square dowels, which provide better load transfer over round dowels and also reduce edge curl of the slab.
• Knockout sizes meet both ACI and PCA recommendations for the design of tongue and groove key joint.
• Tongue and groove design provides excellent load transfer characteristics for heavy, wheeled traffic and prevents uneven settling associated with aggregate interlock
• LOCKING-TAB™ stakes provide a positive interlock between stake and key joint that eliminates floating or rising from the stake, minimizing high spots. The stake profile features a non-twist design which allows the stake to be driven at a straight angle.
• Saves on installation time … stake quickly interlocks at any point with key joint, reducing time to place stakes precisely.
• Eliminates costly form stripping and saw cutting. Replaces the slow and costly method of checker-board placement of concrete.
