Self-Assembly, No screws used. The Green way to compost. Please note - all UK Redwood timber has been high pressure and vacuum treated with preservative which allows for a 15 year warranty on our composters and raised beds. Colour of wood may vary from images shown as a result of the treatment process. Also note, you may receive your order and the timber may be wet, this can be because it has stood out in the rain during transit or it can be the timber has not dried out from the preservative treatment process. If the composter is received with the timber wet you may also notice some mould on the timber this will disappear when the timber dries and will not affect the operation or the warranty we give. This will not affect the use of the composter or raised bed, however there may be some warping and twisting of the timber as the timber dries. When timber dries out there may also be some shrinkage, however this can be mainly mitigated by ensuring all the screws are used in the installation and they are firmly secured into the timber. 45cm High 3 Tiered Raised Beds Extra Modules - Blackdown Range Our 3 Tiered Raised Beds Extra Modules can be bought in three different width sizes; 25cm, 50cm and 1m (100cm) These extra modules consists of 15 planks, 4 posts and screws; and will join on to the posts of your existing 45cm high 3 tier raised bed.
