Q Deck Winchester Pattern Decking 32mm x 150mm. Not all lengths are stock items so please allow 5-7 working days for delivery. Q-Deck Winchester style decking is made from high quality certified softwood. Its finished size after machining is 27 x 144mm and is a reversible profile, meaning either the grooved or ribbed side can be used uppermost.. Being one of the 2 wider profiles means using fewer deck screws per area. Having a proud profile such as this board can improve grip characteristics.
