Add sheltering walls and protective shade to your canopy with the ShelterLogic Max AP Canopy Enclosure Kit with Windows. Quickly converts your 10'L x 20'W Max AP canopy (not included) into a walled and windowed shelter. Tough, ripstop woven polyethylene walls boast UPF 50+ sun protection, and a UV-resistant treatment inside and out blocks more than 98% of harmful UV rays. This rugged material has been constructed with heat-welded seams for a stronger bond and extra water resistance, and it's treated with fade blockers, anti-aging, and antifungal agents. Clearview windows on either side allow for extra light and visibility inside the shelter.
