Bifid corbel with curved arms, able to raise the hooking point of the lantern with respect to the fixing level of the arms.
Handmade, made to measure in any size, ask for a quote.
This one that we illustrate in the photo, at the end of each arm, against the wall of the house, has fixing plates that require the use of STOP FISCHER dowels.
It can also be made with clamps that will be "walled up", the cost is the same.
