30 Jouplast Adjustable Decking Support Risers Adjustment between 50-80mm Used but in great condition - These were bought brand new and used under decking for around 3 or 4 years. Unfortunately the decking had to come away to make room for an oil tank, therefore the risers were taken up and stored away in the garage and are now no longer required. Collection Only - 4 Miles West of Carmarthen Town. Sorry "No Postage" currently as the quantity makes them quite bulky and heavy to ship. Any questions, please ask.
