Shipment and delivery
mcr LAM louvered vents are supplied factory assembled, except for additional external
flashings, higher base assembles, etc. which, if required, come separately. The roof curbs, i.e.
additional base assemblies, always come separately. The reason is to protect the different
components from damage during transport and avoid road safety hazards. The vents can be
unloaded manually or by means of universal loading equipment in the presence of a person
authorised by the manufacturer.
