The Sigma Heavy Duty Parcel Box is one of our newest products. The box has been specifically designed due to the high demands from our customers.

There is a separate letter box and parcel box compartment.

The Parcel Box is an easy and convenient way to receive parcels when you are not at home, for many of our customers it has always been an issue not having a secure place to store their parcels. We aim to eliminate this problem by creating our very own parcel box.

Our Outdoor parcel box is manufactured from high grade, anti-rust coated galvanised steel and accepts large parcels measuring up to 400mm length – 300mm width.

Our parcel box is based off our popular W3 rear access series. The box includes a standard letter flap opening as well as the newly designed parcel box opening. Integrated into the box is additional Anti Theft Teeth designed to deter mail theft of your post and parcels.
