I am looking for a replacement shed door to fit an aperture of 1770 x 880. Looking at your JB Kind Unfinished Solid Pine External door, would the size 1981 x 915 be able to be cut down to my required size? I don't see any trim tolerances quoted for this product?
The JB Kind Un-Finished Solid Pine External Ledged And Braced Gate have a 5mm trimming allowance from each edge.
