Suitable for...
Our Parcel Box and Double Pillar letterbox share the same style of installation bracket.
There are two forms of installation. Bolting onto a concrete slab, or cementing into the ground. Depending on which one you've ordered, follow the steps below to install your parcel or pillar box.
The installation brackets we provide for the Double Pillar and Freestanding Parcel Box are universal and can be modified to suit your desired installation method.
Single Pillars still use the legacy install bracket for now which means a purpose built bracket is supplied based on your order selection.
Double Pillar and Parcel Box
Supplied will be a top hat piece plus two leg pieces.
Into Ground
For cementing into a hole in the ground, attach legs to the top hat with the supplied M8 hex head bolts and matching nut and washer. Dig a hole to suitable size, place bracket inside and fill with concrete. Check that the bracket is level before leaving to set. Once set, attach letterbox to bracket through base of box. For Double Pillars, the lower back panel can be removed by undoing the 2x machine screws found inside rear door. This allows access to the base of the box. For parcel Boxes, simply open the rear door.

Onto Concrete
For bolting to a flat horizontal concrete surface, disregard legs and bolt the top hat to concrete surface (M8 concrete anchor screws recommended, not supplied). Place the letterbox down on top of bracket and attach using supplied M6 machine screws. For Double Pillars, the lower back panel can be removed by undoing the 2x machine screws found inside rear door. This allows access to the base of the box. For parcel Boxes, simply open the rear door.

Single Pillars (Legacy Method)
Onto Concrete Installation
When installing onto a concrete slab, the installation bracket will be supplied already attached to the bottom of the box.

Pillar Concrete Install Bracket
You will need...
- Dynabolts
- Drill
- Firstly remove the bracket from the bottom of the box by unscrewing the screws in the nutserts.
- Then simply bolt the two outer extensions of the bracket to the concrete or solid surface through the four pre-drilled holes in the bracket.
- Place the box down onto the bracket and re-screw the screws into the nut serts to securely attach the box to the installation bracket. NOTE: For Pillar boxes, you need to remove the lower back panel to gain access to the base of the box where the bolts attach to the bracket underneath. This can be done by unscrewing the bolts inside the rear door on the two front corners of the shelf. There are two tabs at the base of the panel that slot into the two slots in the base of the box and the installation bracket to hold the panel in place.
Done!
Into Ground Installation
When you receive your Pillar for into the ground installation, the bracket will be supplied separate due to its size. It has a base plate and four prongs that are inserted into the ground.
For Pillars, the bracket will be inside the bottom compartment, which can be opened by undoing the two allen key bolts inside the rear door to remove the back panel.

Ideally the flat base plate will be flush with or just above the ground the ground. Both parcel boxes and Pillars have a false floor so make sure to account for this.
- Place the four prongs into the four holes, ensuring it's level.
