You can use this chain for both indoor and outdoor applications. It is available only in a red and white combo. It is available in four different thicknesses – 4mm, 6mm, 8mm and 10mm. This purchase is for a metre of 10mm plastic chain. Simply increase the quantity by as many metres as you want to purchase. If you need 25 metres or more, we also sell this plastic chain (our thickest) by the spindle. Please see our other listings under Plastic Chain for our spindle prices.
