Term of the day : 'DIN Rail'
Standardised metal rail (35mm wide shown here). Used to mount building automation electronics, industrial control electronics, power supplies, circuit breakers, etc. usually inside equipment racks. Other sizes exist including:
15mm (EN 50045, BS 6273) where dimension a = 15mm, b = 8.5mm, c = 5.5mm, d = 1mm
G type asymmetric DIN rail (EN 50035, BS 5825) (differnet profile to below)
