This table is an easy way to ensure you select the most suitable holders for your wooden trellis. The mounts themselves differ in their design, length, load bearing capacity, and price. However, more often than not, only one of these criteria are going to be important, eg. creating the greatest space form the wall for sensitive roses, in which case the 'Classic' or 'Heavy' are your best options. Another frequent focus is compatibility with ETICS and other external insulation walls; the deciding factor here is often the least intrusive anchor-- that is, one which creates the smallest drill hole. Most of our mounts come with a watertight seal (gasket).
