The CPT Concealed Post Base Tie is part of our concealed structural connector range, which combines structural strength with invisibility. The CPT provides a clean, concealed look while providing a 25mm standoff height above concrete. The 25mm standoff reduces the potential for decay at the post end and satisfies code requirements for posts that are exposed to weather or water splash or are in basements. It is part of a concealed connector system that includes the CBT and CPT.

Please check the Corrosion Information to see if it is suitable for your application.

Material

CPTZ - Carbon Steel; CPTSS - 316 Stainless Steel
2.7mm thick (base), 3.5mm thick (knife plate)

Finish

ZMAX^® Galvanised: CPTZ
316 Stainless Steel: CPTSS

Features & Benefits

Manufactured in heavier gauge steel for a stronger connection
The post support blade can be used as a template for location to drill dowel holes
Black powder coated base for a modern appearance
Tested and load-rated engineering data available
Suitable for Glulam and solid sawn timber
It can be installed with either mechanical or chemical anchors (dependant on engineering specifications)
Available in a range of sizes to suit 90mm, 140mm and 190mm posts
The 90 mm size is also available in 316 Stainless Steel for for more corrosive environments such as coastal areas
All pins and fasteners needed for installation are included

Installation

Use all specified fasteners
Post bases do not provide adequate resistance to prevent members from rotating about the base and therefore are not recommended for non‑braced or non‑top‑supported installations
Anchorage Options:
The holes in the CPT tabs are sized for 12mm diameter anchors
For cast‑in‑place anchors, there should be 22mm (±3mm) of anchor above the top surface of the concrete

Design Capacity is the lesser of (1) the Characteristic Capacity multiplied by the NZ Strength Reduction Factor (φ), and applicable the k modification factors following NZS 3603 and (2) the Serviceability Capacity which is the load at 3.2mm joint slip. Design Capacity is the minimum of test data and structural joint calculation.
The Strength Reduction Factor (φ) is 0.80 for nails in lateral loading
and 0.70 for other fasteners
Duration of Load Factor (k1) is as shown. Reduce Duration of Load Factor where applicable. Capacities may not be increased.
Timber species for joint design is seasoned Radiata Pine, which is
New Zealand SG8 minimum.
CPTZs are supplied with three 1/2 inch diameter steel dowels. Alternate 12 mm diameter hex or square head machine bolts may be substituted and will achieve table loads.
CPTSS are supplied with three 1/2 inch diameter stainless steel dowels.
Lag or carriage bolts are not permitted.
Structural composite timber columns have sides that either show the wide face or the edges of the timber strands/veneers, known as the narrow face. Values in the table reflect installation into the wide face.
Downloads shall be reduced where limited by the capacity of the timber post.
