Different models and sizes of templates are available in order to satisfy carpenter's needs: nr. 50, 80, 120 and 160.
The choice of a model depends on the dimensions of the wood that is usually used for joints.
For the choice of a template only the width of the beams to be assembled is determining.
Each template allows to work on a particular range of width.
Greater the template is, greater the cjoint and even more its resistance!
So it's advisable to choose the most suitable template for your needs, so as to guarantee the best allowed charge and a good safety of works.
A small beam needs a small joint and a great beam needs a high resistance great joint! It usually takes one model of template, only.
Each template allows even to realize joints (tenon/mortise) with variable height from 90 to 230-300 mm. according to the model.
