Simpson Strong-Tie Concealed Post Base - Suits 115 To 125mm Square Posts

The CPT Concealed Post Base provides a clean, concealed look while providing a 25mm standoff height above concrete to help reduce the potential for decay to timber, at the post end. Available in 90mm (Black or Stainless Steel), 115mm, 140mm, and 200m sizes, the CPT forms part of Simpson Strong-Tie concealed structural connector range, which combines structural strength with invisibility.Manufactured in heavier gauge carbon steel for a stronger connection, base 2.7mm, plate 3.5mm, finished with ZMAX® Galvanized. 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 (dependent on engineering specifications). The 90 mm size is also available in 316 Stainless Steel for more corrosive environments such as coastal areas. All pins and fasteners needed for installation are included.When installing, 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.

Shipping Policy

Australia-wide Shipping

We ship to addresses across Australia from our network of warehouses and suppliers. A small number of remote locations may not be eligible for delivery. If your address is one of them, we'll let you know promptly.

Your order may be sent from a wholesaler, warehouse or retailer partner, so the packaging may not always show the DEAL FIRST name.

Shipping Costs

Shipping costs are calculated at checkout based on your delivery address and order. You'll see the total before you pay.

Special Orders and Backorders

Special order products refer to items that are not standard inventory or items currently out of stock that must be requested directly from an external supplier. By placing a special order, you acknowledge and agree to the unique processing restrictions outlined below.

Dispatch Timeframes

Unlike standard stocked items which typically ship within 1–2 business days, special order items require additional fulfillment timelines.

• Standard Stock: Dispatched within 1–2 business days.
• Special Orders / Backorders: Expected dispatch ranges between 5 business days to 4 weeks, depending on supplier availability and transit logistics.

Any estimated delivery windows provided at the time of purchase are guidelines and subject to supplier supply chain fluctuations.

Delivery Times

Estimated delivery times, counted from when your order is dispatched:

• Metropolitan areas: 2 to 5 business days
• Regional areas: 2 to 7 business days
• Rural and remote areas: 3 to 10 business days

Tracking

Once your order ships, we'll email you a tracking number where the shipping method supports tracking. Larger orders may arrive in more than one parcel.

Late or Missing Parcels

If your parcel hasn't arrived within the estimated time, or tracking hasn't updated for several days, please contact us with your order number and we'll follow it up with the carrier.

Special Order and Backorder Cancellations

Once a special order or backorder is placed with our supplier, the order cannot be cancelled. Cancellations will only be authorized if the supplying manufacturer permits a penalty-free cancellation to us. If any supplier administrative fees or restocking fees are incurred during a requested cancellation, these costs will be passed on to the customer.

Returns and Refund Policy

At Deal First, we aim to provide you with the best shopping experience. Please review our return and refund policy below:

Consumer Guarantees and Faulty Special Order Items

The restrictions placed on cancellations and change of mind returns do not impact your statutory consumer rights. If a special order item arrives damaged, is structurally faulty, or fails to meet legal consumer standards, you remain fully covered under Australian Consumer Law (ACL) and the manufacturer's operational warranties. Faulty items will be repaired, replaced, or refunded in accordance with your legal rights.

Damaged or Defective Items
If you receive an item that is damaged or defective, we will provide a prepaid shipping label for you to return the product. Please contact us as soon as possible to arrange this.

Special Order and Backorder Change of Mind Returns

Our standard return and exchange policies do not apply to custom configurations, non-stocked products, spare parts, or special order items. We do not offer refunds, credits, or exchanges for change of mind on any special order goods. Please ensure all product specifications, sizes, and compatibility requirements are fully verified before finalizing your purchase.

Restocking Fees
Items returned due to buyer’s remorse, incorrect purchase, or changes in preferences (e.g., no longer wanted/needed, found a better price) may incur a restocking fee of up to 20%. This fee also applies to non-warranty returns.

Shipping Damage
If your item arrives damaged due to shipping, please refuse delivery if possible and contact us immediately. If you cannot refuse delivery, retain all packaging materials and notify us so we can process an RMA.

Prepaid Shipping Labels
When we provide a prepaid label, you must drop off the item or schedule a pick-up with the carrier within 7 days of receiving the label.

Refund Processing
We will typically issue a refund once the returned item is in transit with the carrier. However, please allow up to 15 days from the shipping date for the return to be processed and your refund to be issued.

Since we work with multiple suppliers, each may have their own return procedures and timelines. We will coordinate with the appropriate supplier to handle your return in a timely manner.
