Dome & Kerb Measuring

Measure overall dimensions of the opening (length x width). Standard roof opening sizes / dome sizes are detailed below. All domes in the Mardome range can also be specified to be fixed directly to an existing builders upstand, and where necessary these are supplied with a 'direct fix' adaptor to enable this. An optional Mardome kerb adaptor allows standard size domes to be fitted to non-standard size upstands.
