Series M4045 is a wooden canvas frame which owes its name to a side view of 40 mm and a rear side with an edge of 45 mm. The front view of the frame is 20 mm. This frame is available in three different colours. The frame is available in various standard sizes, but is also custom made. The canvas frame is supplied without suspension wire or eyes, but the moulding is often combined with this suspension system. Sizes larger than 70 cm x 100 cm are supplied as four separate mouldings with a Mix&Match system. This is very easy to assemble.
