The internal bracing adds strength and ensures that your tools, gardening equipment or larger household objects are securely stored. This shed comes with a roller shutter door which makes access in and out of the shed easy, ensuring your backyard is kept neat and tidy. *The Pale Eucalypt bushranger comes with a Surfmist door. Absco sheds are designed to be anchored to a concrete slab (not supplied). Bolt down kits are not included with this shed kit. Assembly is made easier with the help of pre-drilled holes and Absco’s patented SNAPTiTE technology that allows for panels to lock into channels without the need for screws. Absco recommends working at waist height using trestles and timbers for a faster build. 2-3 people are required to build sheds larger than 1.5 x 1.5m to assist with holding panels upright during the final construction. More people are required for larger structures. This app is free to download from the App Store and Google Play store.
