Product Description
Bertram A3 Straightline Drawing Board with Parallel Motion. Compact A3 size 530mm x 400mm laminate drawing board, 14mm thick. Chromed prop stands the board at the correct working angle and when folded forms a convenient carrying handle. The parallel motion has reliable, adjustable, underboard cross cord system which can easily be replaced and runs on smooth brass bearings. The aluminium reversible parallel motion has perpex edges which are marked 1:1; 1:2 in centimetres and the reverse edge has 1:5; 1:2.5 for scaled drawings. It takes 10 seconds to unscrew the ruler from the sliding carriage with the metal to metal fittings(see picture) and the same to refit. The edges of the rule are "captured" to ensure continuing stability. There are 2 rubber feet on the front edge to give a good grip to the working surface The ruler blade is similar to the scales we supply with top of the range drafting machines. The aluminium centre gives strength whilst the clear perspex ruler edges allow you to see your drawing. The markings are engraved on the underside so they will not rub off. The perspex inking edges are raised from the board so that your drawing ink will not smudge. Weight is only 3.5Kg so it's easy to carry and yet very strong. Made in Italy by one of the oldest makers of scale rules you can be sure of complete satisfaction whether you buy this for work, study or pleasure.
