Have installed in beam in concrete wall due to opening. The beam rests on concrete brick.
Question: how much surface does the beam need to rest on, is 300 mm enough?
Also, question about what should be used for filling between the beam and concrete, need to fill about 20 mm. Should be something that doesn't shrink and can handle the load.
Grateful for tips.
