Double Bar Plate Dowels for Saw-Cut Contraction

Double Bar Plate Dowels
for Saw-Cut Contraction Joints
Designed to Deliver More Serviceable Slabs
Superior Engineering for Optimal Joint Performance
Concrete slabs-on-ground must be able to withstand the
repetitious, concentrated loads and abrasion of wheeled traffic
at the weakest point—the joints. The “W” Basket assembly
used in the “strategic reinforcement” design helps you reliably
deliver a serviceable slab in a competitive environment.
Utilizing McTech’s unique Single wire, double bar plate and
compressible center geometry and a factory applied
debonding agent,
the “W” basket assembly helps you:
• Collect your retainage
• Reduce your call backs and save labor
• Optimize the amount of steel in a project
• Limit your liability
• Deliver cost-effective slabs-on-ground
• Limits differential deflection across joints to minimize
joint spalling
• Allows the slab to move horizontally in both directions
• Minimizes restraint due to horizontal shrinkage
• Provides an increased bearing area at the joints, reducing
bearing stresses
• Is a more efficient use of steel when used in the “strategic
reinforcement” design
• Provides an eight- or four-inch saw-cut construction
tolerance
• Single wire design strong and efficient.
• Double bars with compressible center.
• Provides immediate vertical load transfer with a thinly and
evenly factory-applied debonding agent
With the unique “W” basket shape of the dowel support frame,
EZbasket W will have a greatly reduced carbon footprint as
compared to many other dowel baskets currently on the
market… EZbasket W… the most sustainable basket.
Performance Based Dowel Design
Fast, Simple Installation
• Requires fewer man hours for installation than
conventional methods
• Easy to handle—can be carried and installed by one person
during concrete placement
• Allows for sub-grade leveling after installation to prevent
rutting, restraint and cracking
• Construction tolerances allow for misalignment without
causing restraint in the panels
• Eliminates obstacles for the laser screed
• Fully welded assemblies, offering stable dowel support
during installation
• Unique shape allows more baskets per truckload
• Bundled and shipped on skids, for easy handling
• Shipping wires do not have to be cut during placement*
• Custom and stock baskets are available through our
national distribution network
In areas subjected to wheeled traffic, heavy loads
or both, joints with dowels are recommended.

Double Bar Plate Dowels
for Saw-Cut Contraction Joints
“W” EZbasket™ Specification
• All EZbasket™ products will be supplied by McTech Group Inc. 1-866-913-8363.
• Plate Dowels will be cut from hot rolled plate per ASTM A36 to within 0.010" of specified length.
• Side frame supports will be fabricated from 1/4” diameter cold drawn wire per ASTM A108 grade
1010-1020.
• Plate Dowels will be welded (on one end only) into the side frames, with the welds alternating along the
length of the assembly.
• Specially designed elastomer with compressible material will be fitted between the Plate Dowels and
should extend to within plus or minus 0.1875" of 2/3 the bar length.
• Eight gauge wires will be welded across the side frames at approximately 3’ o/c to keep the assembly
stable during shipping and installation or as needed.
• The finished assembly will hold the Plate Dowels to within plus or minus 1/8" of the required slab
placement depth.
• The assemblies will be manufactured so that they stack on top of each other for transportation and
remain stable under concrete placement.
