A 10-ft by 12-ft retractable pergola that lets the shade follow the sun instead of staying fixed. The canopy rides on a sliding track, so the handles and lock buckles set coverage anywhere between open sky and full shade over a dining set or lounge chairs. The 180 g polyester top is sun-proof, drizzle-resistant and CPAI-84 flame-retardant, and the arched roof line keeps rainwater moving off the fabric. Underneath, a powder-coated metal frame with triangle bracing, pre-drilled footplates and 16 ground nails holds firm on decks, lawns and patios.
