These gratings are known as "Long Gratings" and are 3ft in length. They can be used as drainage gratings or ventilation gratings.
The lattice pattern is one of the oldest designs for gratings and is especially suited to period properties and conservation areas.
The lattice pattern is only available in 3ft (914mm) lengths, it is not suitable to be cut. If gratings shorter than this are required, square hole pattern is the ideal alternative and is available here
The 4" (100mm) wide lattice grille is often used in the wall as under front doorstep ventilation. There is an option to add flyscreen mesh although the mesh will reduce the free air flow to around 22,000mm2.
The larger size, 6" (150mm) and 9"(225mm) Lattice gratings are more likely to be found as floor grates.
Please see our cast iron bearers to support these grilles.
