Here we will go into more detail on the 'classic wooden trellis' -- addressing the design of the lath heads, how to determine the measurements for the laths, how to determine the spacing between the slats, and other techniques for extending/dividing lath axes. Additional information can be found in the sections of the different trellis anchors and mounts, including info on maximum recommended distance (between trellis mounts and wall), how to attach the trellis to the facade, and which mounts to use.

The vertical laths mostly have a square cross section of 25 - 27 mm and therefore appeal delicate. A thickness of 30 mm is quite strong, but now and then necessary in the case of heavy fruit espaliers.
Abhängig vom Lattenquerschnitt sind aller 1,5 - 2 m Querriegel erforderlich, um das Spalier ausreichend zu fixieren.
The distance between laths is approx. 15 - max. 35 (40) cm, depending on aesthetics, wood cross section and type of climbing plant. 22 - 25 cm is standard.
Even the cross bars slightly protrude, about 5 cm.
Usually lath heads are bevelled (receive a 45 degree mitre cut). However, other forms and designs are also possible.
Vertical laths on large trellises are easily lengthened, cross bars less. Sometimes gaps are necessary, also to create sensible dividing lines.
How are the plants attached to the system? Either with their own tendrils (Continuous Bloomers and Clematis), or additionally with binding materials as shown here.
