Clamber Stacks

A clamber stack is a timber and rope climbing unit built to resemble a natural pile of sticks. Instead of one fixed route, children choose their own way up and across using climb nets, scramble logs, drop ropes and balance beams. Support ropes on designs such as the Wyre Clamber Stack give developing climbers extra stability.

Yes. Many designs come with a stainless steel slide, including the Sherwood, Beacon, Brightstone, Nene, Haldon, Afan, Tarn and Cannock stacks, and the Nest Clamber Stack has a 0.9m plastic slide. See our full range of playground slides.

Yes. The Kielder Clamber Stack is available with a duo or triple deck castle, and the Sherwood Clamber Tower Stack adds castle-themed panels, an arched ladder and an inclined rope bridge. They combine climbing with role play and pair well with our castle playground equipment.

Clamber stacks require suitable impact-absorbing safety surfacing to help reduce the risk of injury from falls. Options include wet pour rubber, rubber mulch and engineered wood fibre, depending on the equipment's critical fall height and the playground's requirements.

The type and depth of surfacing required depend on the clamber stack's critical fall height and safety area. Caloo can advise on suitable surfacing options to meet the relevant playground safety standards.

Yes. Clamber stacks work well as an upgrade to an existing playground or as the centrepiece of a new natural play area. Our free design service can help you choose the right stack and plan the layout around your space.

Unlike traditional climbing frames with structured platforms and climbing routes, clamber stacks use irregular timber logs and ropes to create a more natural, free-form climbing experience. Children can explore different routes, climb over logs and navigate rope features, developing balance, coordination and problem-solving skills through play.
