The SD-3 Low is a precision-made outward-opening single timber door for garden buildings, log cabins, and summerhouses. Frame size is 886×1918mm, with a clear opening of 706×1749mm.
Anti-Warp Engineering
Built from 45mm spruce profiles, it uses laminated spruce on components over 160cm to reduce warping and seasonal movement while keeping a solid-timber look.
Weather-Proof from Day One
For all-weather use, it includes 4+6+4 ESG double glazing, silicone sealing, rubber draught seals, a spruce casing with rubber gaskets, and an aluminium threshold strip for extra protection at the base. Fully adjustable hinges (set with a standard allen key) allow accurate alignment over time, with black covers for a clean finish.
