Design and engineering experts widely acknowledge that the floor is the most
important component of a warehouse or distribution centre. The capabilities of the
floor are determined by storage and racking systems and the sophistication of the
vehicles used to handle the warehouse contents.
Poorly positioned joints or cracks in high-traffic areas can:
• Slow down the movement of forklifts and other materials handling equipment
• Cause unnecessary wear to tyres, wheels and bearings
• Potentially cause instability with loads
Uneven floors can also result in the same negative effects and slow down production –
adding to running and maintenance costs.
Why use high performance dowels?
Dowels are required at joints in concrete slabs to transfer vertical loads across the joint
and minimise differential deflection between slabs under load.

Available with colour coded one-piece sleeves
6 mm are orange
10 mm are blue
Ideal for perimeter-of-pour dowel applications, i.e.
at construction joints
No need to drill forms to support dowels during
concrete pour
Nailing flange provides secure attachment to form
boards
Flange on sleeve ensures dowel is perpendicular to
form board and is stable.
Each sleeve is fitted with an internal spacer to
prevent collapse caused by pressure of concrete –
the spacer is easily displaced into the apex of the
sleeve when inserting the Diamond® plate
Sleeves moulded from durable, non-compressible
material
Sleeves fitted with double-headed nails – second
head on nail acts as an anchor to help retain the
sleeve in the concrete when stripping the form
boards
Reduced likelihood of sleeve knock-off when
placing steel reinforcement mesh
Simplifies form removal
Dowel plates available in black, galvanised and
stainless steel
Wide dowel plate at point of maximum load
reduces stress on concrete
Can be integrated into other formwork systems
Ergonomically designed, user-friendly packaging,
complete kit with installation instructions

PD3 Dowel® Cradles and Plate Dowel
Cradles™ are well suited for contraction
joints in concrete slabs and pavements.
As well as efficiently limiting deflection, the
3 metre-long fabricated cradles ensure
the dowels are set at the exact height for
the specified slab thickness, and at precise
spacing to minimise installation time.

Features & benefits:
• Available in 6 or 10 mm thick dowels spaced at
450 or 600 mm centres, and for slab thicknesses
ranging from 150 to 300 mm
• Dowels are colour coded:
6 mm are orange
10 mm are blue
• Tapered plate dowels 300 mm long; made from AS/NZS 3679.1 GRADE 300 steel

capacities and deflection characteristics as
rectangular Plate Dowel Cradles™.
HOW TO SPECIFY
Specify PD³ Dowel® Cradle OR Danley® Plate

Danley’s Dowelmaster® sleeves allow square dowels to move
both parallel and perpendicular to the construction joint as the
concrete slab shrinks during curing. Simply secure the sleeves to the
construction joint forms with the optional nailing plates; pour the
concrete; strip the forms and insert square dowels into the sleeves –
ready for the second pour.
