Made from carefully selected knot-free, kiln-dried pine in sizes 12” to 84”.
Bracing slots are provided on all sizes from 48” and above.
Open-ended mortice and tenon corners make squaring up easy to achieve and maintain.
You need 2 cross braces - a yellow and a purple. eg:
if you are making a frame 48'' x 66'' then you need a 48'' yellow and a 66'' purple
or vice versa. It does not matter which colour as long as you have a yellow crossing over a purple.
