What sizes are the Iron Works Hit & Miss Vents available in?

What sizes are the Iron Works Hit & Miss Vents available in?

The Iron Works Patterned Hit & Miss Vents are available in two sizes: 225mm × 82mm (single-course, suitable for standard airbrick positions) and 225mm × 150mm (double-course format). Both sizes are available in all three finishes: Antique Black, Polished Lacquered, and Polished Brass.

Which Bracket Should I Use?

Which Bracket Should I Use?

We manufacture a wide variety of brackets for many different cast iron gutter and pipe profiles. More common types are the rise and fall, top fix and side fix rafter and the holderbat or pipe clip.

We can also offer traditional drive brackets, repair brackets and fascia brackets in both steel and cast iron.

It is always advisable to replace like with like because quite often the brackets form and important part of the buildings architecture. Occasionally buildings have special decorative brackets and our UK manufacturing allows us to produce small quantities of bespoke brackets when required.

What does “hit and miss” mean on a ventilation grille?

What building types is the Iron Works Hit & Miss Vent in Polished Lacquered suited to?

What building types is the Iron Works Hit & Miss Vent in Polished Lacquered suited to?
