Made with laminated strips to prevent any chance of warping and creating a much stronger piece of wood than a single strip.
Crossbar Guideline:
The information below indicates how many crossbars you will need for your frame;
1 x Crossbar at 60cm-165cm
2 x Crossbars at 170cm-235cm
3 x Crossbars at 240cm-300cm
E.g. A stretcher frame of 225cm x 150cm will require 1 x 225cm Crossbar and 2 x 150cm Crossbars.
