Adjustable Decking Pedestals 30–60mm | Pack of 10

Getting a perfectly level deck or shed base can be a real challenge, especially on uneven ground. These adjustable decking pedestals take the frustration out of the job by letting you fine-tune the height anywhere between 30mm and 60mm, giving you a stable, even surface without the need for digging or concrete. They work equally well for raised decking projects, garden shed bases, and outdoor structures, making them a genuinely useful addition to any DIY toolkit.

Each pedestal is designed to support joists made from wood, plastic, aluminium, or composite material, so they'll fit in with whatever decking system you're already working with. The fixed head system locks joists and risers together securely, and with a rated load capacity of over 1,600 kg per square metre when using the recommended number of supports, you can trust these to handle the weight of a fully built deck with ease.

One of the quieter benefits of using a pedestal system like this is the airflow it creates beneath the subframe. Keeping timber or composite joists off the ground reduces moisture build-up and helps extend the life of your decking considerably. This pack of 10 is a practical starting point for smaller projects, and with the broader range of heights available across the product line, you can mix and match to suit more complex or sloping sites.
