A range of straight sleeves to accommodate one, two or three cavibricks. (High throughput cavibricks are designed to be used singularly or can be locked together to form larger brick-sized ventilating units.) When connected to a cavibrick the combined length is sufficient to accommodate all popular cavity wall widths.
The three standard straight sleeves are: 75mm x 225mm, 150mm x 225mm and 225mm x 225mm. We recommend sleeves are protected with a cavitray where they pass through the cavity, to comply with NHBC/best practice. (See Sleeve and Duct Cavitrays.) § Fold-flat design minimises storage space. § Packed in boxes containing 50 number. § Smaller quantities available.
